[GRASS-dev] [grass-code I][544] Map Display crashes whenzooming (too much) in!

[Patton, Eric]

Yes, I can confirm this error as well. The trick to getting it to show up is to zoom in until you get the 'Max zoom in reached' tcl dialog box, then immediately after you dismiss this window, click on the 'Display Active Layers' button on the Map Display window.

Using 6.3.cvs from today on Ubuntu 7.10.

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?

Michael
