IA v6.1 is now supports both ToB and BG2:EE. There was only limited amount of testing on the latter platform so we can't promise a completely stable and bug-free experience. Keep also in mind that BG2:EE is a work-in-progress by itself, with many potential issues. If you stumble upon something, report it here and we'll do our best to fix it.

If anybody wants to help out with testing of upcoming versions, send me a PM.
