Just installed v17 beta: Windows 7 32-bit. Unfortunately, it seems unusable. As it starts importing files (whether using the auto-import timeout or manually via Tools -> Import), the whole application freezes, until Windows asks whether to shut it down or wait for a response. Waiting doesn't help, the process must be killed every time.
Interestingly, the same thing happened when uninstalling (Windows had to force-kill the uninstaller).
I hoped to take advantage of the special upgrade price offer, but I cannot pay for a product that's *that* broken. I'll stick with v14.
