IDE freezes when opening a project, under Git control

When opening a project under Git control can cause the IDE to freeze.
The most common reason we have found is that the incorrect git binary has been specified.

To check which Git binary you have specified look at the following in the IDE:

1) Tools | Options | Version Control | Git
2) Git Executable

It SHOULD be git.exe as shown here:

People commonly make the mistake of using git-cmd.exe which is what causes the IDE to freeze.

git-cmd.exe creates a process, opens a Windows command shell, and sets The PATH environment variable to some of local git directories
