Despite having circumvented the problems caused by the new Windows Vista UAC – as described in an older blog entry of mine and found all around the internet, git sometimes still has problems.
At work, my team collaborates with SVN and commits to our company svn server. I am using git as an SVN client, because it is more convenient for me; with no problems on my Gentoo (dev) box, but I never managed to check out on my Windows laptop.
