Hey, again I'm sorry to keep you waiting. I'll test the new version on both systems today in the late evening, with and without TrueCrypt.
I've found a minor bug (?) concerning "default" applications (the way some programs, for example Office 2007, map the associations), but I need to take a look at the registry first to understand it before posting. If you've got the chance to install Office 2007 with default associations maybe it will be easier to explain.
