After experiencing crashes with 1.0.5 in XP Pro, I discovered the "themes fix" in this forum which seemed to work. However, I am still experiencing random crashes even when the app is minimized to the tray and I'm working on another completely unrelated app. While it's rock-solid on my W2K/SP2 box, I can't avoid concluding that it's unstable on XP for the time being.

Got 105 and 12beta on two different XP systems. It's not a matter of if the app will crash, but when. I'm sure it will get straightened out in the next rev or two, but for now, Gnotella and XP don't mix.
