I can't seem to save an environment variable. I use Settings -> Environment..., click on Environment Variables, click on the Add button, enter a Key and Value, click on OK. The environment variable shows up in the list. I then close the Environment Settings window. When I reopen the Environment Settings window, the environment variables list is empty.
I am using the MacOSX build of version svn 5000.
EDIT: I found the problem. I tried it in the MacOSX patch 2 version, and it worked. The problem is that in the svn 5000 version, the Environment Settings window is too big--the bottom of the window is out of view, even though the top is flush against the top menu bar. I couldn't see the "Cancel" and "OK" buttons at the bottom, so I didn't even know they were there.
