Comment 20 for bug 879895

So, funny thing. I just sat down with two computers (my ubuntu 12.04 and my husband's windows 7 netbook) and conducted a few screensharing skype calls. For some reason the only way I can execute an action is if my husband typed a short message to me in Skype. So for example I'd click CTRL + TAB and nothing would happen. Then my husband would write "ok" in the skype chat window and as soon as I received that message the CTRL+TAB command would go through.

The best I can figure is that the only way my machine can "refresh" is by receiving these outside pings. It doesn't matter what it is. Just as long as it comes. So basically I can type a command into terminal and press enter. I won't see the command and it won't execute until I tell the person on the other side of the line to send me something in the chat window. Then the command is executed and their screen refreshes.
