Interesting sidenote(s): I have the same problems with PPT2010 as everybody else, but i cannot remove BC because i need access to the OS X partition.
1. i have VMware workstation VM on my 64bit win7 side. The VM is a 64bit version of win7 with Office2010 inside the VM also. Everything is fine INSIDE the VM. keyboard works fine. Outside the VM, in the 'native' Win7x64/Office2010, i get the crash. VMware traps and converts keystrokes, obviously.
2. cut/paste into PPT text boxes works on the non-VM native/host Win7 side (i have put text in Notepad and C/V'd into the PPT text boxes fine.
3. the dialog boxes in ppt accept keyboard input fine! (i opened an existing PPT, opened a search/replace box and entered text and REPLACED ALL, and worked fine)
4. oddly, the on-screen keyboard (Accessibility options) crashed PPT as well. [Obviously interfaces with the problem kybd driver]
so, i am stuck with PPTing into a VMware VM , and then moving the finished PPT over to the host Win7 for printing, Camtasia, email, etc (since i cannot remove the BC3.2 for other reasons so far).
just FWIW--i will call apple on this later this week when i get time--unless somebody else posts their answer here earlier. gm
