Hello,
I just wanted to say that SourceTree is a great tool. I'm using it on Windows 8.1 and it works almost perfectly.
The only bug, I've noticed, happens when I use the Fetch command (I disabled the automatic fetch option, because of this bug)... It often finishes with a "Blue Screen of Death" (ERROR: 90% of the time -> BAD_POOL_HEADER / 10% of the time -> something about DRIVER)... Then when I reboot my computer, the git objects that were fetched are corrupted.
Is this possible that you try to fix this issue ? Then you could say "Sourcetree supports Windows 8!".
Thank you very much for providing such great tools!
