When I have a file open in emacs for awhile, and the windows is out of focux, the window will hang if I click on it. This is with the GUI form of emacs. I found a related issue that said to use the mouse and select "File | Save As..." and then cancel the "Write file:" window that appears. This is a bit of an inconvenience and should be resolved. In case it makes a difference, I am running multi-term in emacs.
