That's the old story... change one bit in an installation and you can point vice versa if trouble occurs...
I've just checked out TI OS 3.2 beta and how funny - now things work much better! No trouble or usb errors any more when closing and reopening the TI VST in my host... but I know, that's again my XP, isn't it

? ...funny, now some Mac users seem to have trouble they had not before.
I am not angry or something... I can imagine how difficult it is to write a software like TI OS... to me it just looks like OS 3 still needs some tuning to work perfect... and as long as access works on that to make all work I am happy...
