Arlene,
I'm not sure, what is causing your problem and if it is the same problem.
The problem I have encountered was that the labels were moved approx. 300 meters. This matched exactly the difference between coordinates in two often used coordinatesystems in Denmark.
The problem was that when the workspace was written the coordinates were written using the first coordinatesystem. But when the workspace was reloaded, the coordinates were interpretered using the second coordinatesystem.
If you look at a workspace in a text editor, you'll see that when MapInfo creates a map, it involved a number of statements:
1. Create the Map with the layers.
Map From <list_of_layers> ...
2. Set coordinatesystem, center and zoom
Set Map
CoordSys ...
3. Setup the layers
Set Map
Layer 1 ...
Layer 2
Layer ...
If you add a print statement, that prints the current coordinatesystem of the map after the first Set Map and after the second Set Map, you can see if MapInfo is using different coordinateystems. The print statement is this: Print MapperInfo(FrontWindow(), 18)
Here is a short sample:

Subject: [MI-L] RE: Labels
Hi,
I've also had this problem and it wasn't caused by packing -- the arrows from the labels point to the correct points (correct label with correct point) and I haven't packed the table. Not sure if it is caused by coordsys difference. The labels aren't really in the wrong place -- the lines/arrows pointing from the label to the point are hundreds of miles long (I've had one go almost to South America when the point was in Central Florida). For example, I have a map layer with an extent of 20 miles and have a few labels pulled off some points, maybe 1/2 a mile from the point -- just enough so it is readable in my layout window. I re-open the saved workspace and those labels are now hundreds of miles away from their points. If it was a coordsys problem, should I expect the difference to be the distance between a point in one coordsys and the same point in another system? Or is the coordsys difference just causing the labels & lines to "fly" all over the place?

Hi,
Just wanted to share some insight on this issue.
This problem is not only related to packed tables. I can slo be related to raster layers ...
Imagine this:
1. You have a map with a bunch of layers and a raster layer. Thie raster layer is not visible, but in a different coordsys 2. You save a workspace with the current view of the map, the coordsys is not the same as the raster layer
3. You reopen the workspace. Now it gets technical:
3a. When a map is created thru a workspace MapInfo starts by adding all the layers 3b When it has added the layers, the map window has the coordsys of the raster layer 3c. Now the settings for the layers are applied, and also the costum labels - coordinates are not using the coordsys of the raster layer 3d. Finally the settings for the raster layer, se the zoom level and turns off the raster layers visibility
4d. Now the labels turn up in incorrect positions.
Did you notice the problem ?
The problem is that when saving the workspace, the coordsys is not the same as when reloading the workspace again. This might interfer with the position of the labels - and I guess also with cosmetic objects !?
So, be aware when using raster layers in a different coordys then the rest of you layers. BTW, this might be solved with MapInfo 8.5 as you here can reproject raster layers.

Hi
Usually, it happens only on labels that have been moved to some other locations by the user (so there is a line in the wor for this specific label where you find the new location of that label and the row id of the table to which it corresponds) AND only if the table has been packed AFTER labelling (cause when you pack a table, rowid changes, at least the ones that are located after the greyed records).
In this case, the wor you're using is not up to date with the table : some labels in the wor are still pointing to a let's say 3rd row in the table, but that 3rd is not the same object as it used to be...cause the table has been packed inbetween
Don't know if it make sense to you. It's even a pain to explain in french, so imagine in english !!!
David

Hello,
I am using Mapinfo Professional 7.0. Occasionally, when opening a workspace created ion the past, the labels "streak across the page;" that is, labels no longer are located where they should be , but have moved far to the southwest, with their connecting lines stretched from the point map location to the newly moved label. To fix this, I can click "remove custom labels" andf auto label, but then I lose my custom labeling of course. Normally, I click on each labeled data point with the auto-label tool to fix this, but my most recent map is very large, and clicking each data point iss very time consuming. I've searched the Mapinfo knowledge base for a bug fix, but had no success. FYI, this also happened when using Mapinfo 6.0. Also, this problem does not happen consistently. Any Ideas?
