Hi, I'm using git for windows, PortableGit-1.7.11-preview20120710 (I've just upgraded from PortableGit-1.7.6-preview20110709, which also had the problem), on windows 7 (SP1). I find it handy when running "git difftool" to make changes to the file in the difftool (I personally use diffmerge http://www.sourcegear.com/diffmerge/ ) - especially if files are very long, and you can remove spurious new lines, etc. etc. with ease minimizing the number of changes you are going to make in your commit. This is usually no problem. The problem is that, I have found that sometimes files seem to be locked, and whilst the diff program is open, I cannot write to the file - neither from the difftool nor from, say, another text editor. When I close diffmerge, the file is writable again. Logging off and on again and the problem persists. Diffmerge says: "Could not open this file for writing. Try to override file permissions?" [I click 'Yes'] "Error! Cannot open file." Notepad++ says: "Save failed Please check whether if this file is opened in another program" Other programs give similar errors. I've tried running the command both as an administrator and as a normal user, and there seems to be nothing wrong with permissions/ownership on the file. Using the "Process Explorer" Sysinternals tool, I can see that git.exe has a file handle open - and I guess the mode it has opened the file is preventing writes - thing is - it doesn't always seem to do this. Makes me wonder if the file handle isn't being closed properly in these circumstances? If this is by-design, it is not happening consistently, because 99% of the time I can edit no problem.
