Please provide compatibility diagnostics from ISBoxer's Help menu.
http://isboxer.com/wiki/Diagnostics Do you get a crash window? Any further information you can provide?
This goes pretty much any time you're getting new crashes, regardless of how many PCs you have, so we can better understand what is going on.
I'm on the road at the moment, so you'll have to excuse my relative inability to download Trove for testing for the next couple of days. I have it installed at home but Glyph is not cooperating with me over RDP (and I'm just trying to get it to patch stuff so I'm not even using Inner Space yet).
As nobody else has chimed in, I'm currently operating on the assumption that others are not having the issue. (Generally speaking, your question is backwards -- people will check the forums if they are having issues, but people who are not having issues are busy playing)
