Thanks for your input.
I have done a clean install of video drivers perhaps a month a go and I'm using Windows7, so neither of those fixes seem fitting to me. All though thankfully the game looks now much more stable and beautiful than OS1 EE.
For me the crashing has been mostly when viewing items (80% of the time?)
This crash in OS2 was when I was viewing the items in a merchant's inventory in the Seeker's hideout, not Gareth but the other hotshot.
