I had Plus for a really long time and all of a sudden the event log window stopped workin, it juss wont show up at all, I tried to unclick and click it again, I changed it numerous times in preferences, I restarted Messenger, I even reinstalled it, but it still won't work. Any suggestions? It was my favorite part of Plus

The window could be hiding somewhere, perhaps you can try this:

Uncheck Event Log Viewer
Check it again
Immediately press Alt+Space. If a menu popus up, select Move. Use your arrow keys (Up, Down..etc) to move the window until it becomes visible
