I just tried this with cvs compiled from an update of this morning and had
no problems.
In normal mode, if you zoom to less than 1 raster cell, a TclTk message box
pops up saying you've exceeded the maximum zoom.
In explore mode, you can zoom to much less than 1 raster cell.
In neither case did I get a TclTk error like the one below.
I did wait until a map was completely displayed before trying to zoom
again.
I tried this on a Mac PPC G5, with OS X 10.4.11.
Has anyone else had this problem?
