The following errors have stayed in the upgrade from MI 5.0 to 5.5 -
hopefully someone from the list can help.
1. When zooming into a region at close range, it is lost on the map
(although the info tool still sees it). This is frustrating a number of
users who capture data at low zoom extents but require regions as backdrops
to indicate whether they are working within a specific area. The following
code illustrates the problem by drawing a big red triangle and trying to
display it at a 1 km zoom.

2. When panning map windows in both 5 and 5.5, only portions of the screen
are redrawn, creating a staggered appearance within the map window.
Scrolling the map by clicking the mouse wheel will often result in window
full of map "slices" which need to be redrawn to show the map correctly.
3. Having installed MI 5.5, we also get the "... mapinfo.mnu:1020 ... "
error at startup.
