Using 2006, I'm having problems switching from LDT to Map3D and vice versa. If I have used LDT, I can't open Map without logging off and logging back on. The case is the same if I have used Map, then I can't open LDT without logging off and back on. The programs will just lock up when they try to load the .dwt file and I have to Ctrl+Alt+Del to shut it down.

Any suggestions?

Thanks,

Hugh
