Hi,
When you say you get an error, are we talking about a MapInfo.exe error and MapInfo closes losing all data, or just an error - cannot save table? I do what you say quiet a lot, and had one instance on XP that caused so many crashes that I wrote my own cutter tool function. I am convinced the problem there the issue was selection of the records created in the table to get rid of the debris left behind by the standard mapbasic cutter function. There is a possible connection.

Hi Sarah & List
I have managed to reproduce an error very similar to this consistently in MI Pro 7.0 and 7.8 with the following sequence of actions:
Create a new, mappable table, make it editable
1. Draw a region
2. Draw another 'cutter' region that partially or completely overlaps the first
3. Set the first region as a target, and 'Erase' using the cutter region
4. Delete the resulting modified region
5. Undo the deletion
6. Attempt to save the table
The error message is produced, and all unsaved data is lost (transaction files are wiped)
The key operation appears to be the undoing of the deletion (or other modification?) of an unsaved object that has been generated by Mapinfo in an object modification (eg Erase, Split, Combine etc. - these all delete the target objects and insert new ones into the table) as opposed to a user generated polygon.
Significantly, (I think) if the table is saved between steps 3 and 4 then the error does not arise.
I have reproduced the error on three different machines, running Windows XP and 2000 and MI 7.0 (build 26) and 7.8. The error does not occur on MI Pro 6.0.
Sarah - do you think this is the same bug, if so, you might want to avoid using the undo tool when performing object manipulation operations.

Error Message "Unable to update Table xxx" (xxx=name of table)
Using MapInfo 7.5 Windows 2000 Novell Network Netware 5.1, Service Pack SP5 MapInfo installed from snapsot across network.
Error message when table is saved. Error message then occurs, and then the polygon is lost. Or alternatively it seems to wipe several saves.
Have tried the following :
1) getting rid of MapInfo on machine, and reinstalling from disk.
2) Working through desktop only, not on network.
3) Checking polygons arn't exceedingthe amount of nodes in a complex polygon.
4) Clearing out the temp directory
5) changing and checking the temporary environment variable to a local directory.
6) Fast edit is on via map basic window.
7) Looked at Novell Netware site and set client file caching = OFF on server.
8) The users appending data to rather than copying and pasting
9) Checked there is plenty of virtual memory.
10) Turned of fire wall software on the pc.
11) Turned of notification of e-mails etc.
And now ......,, i am totally out of ideas, can anyone suggest anything please.
