Two things I thought I'd mention so they can be placed on the bug list.
1) When I tried to save an HTML photo fusion page while the 3D display was up, TopoFusion crashed.
2) I had Topofusion up with (I think) the 2D plot displayed and decided to start up Google Earth (
http://earth.google.com). Both programs essentially froze and I had to kill both applications several times to finally get rid of them. Probably some graphics resource conflict, and I don't know if blame could really be assigned to either, but it would be better if the programs could fail gracefully.
I have not checked to see whether either problem was repeatible.
