I have mutltiple monitors and somehow skype is pushing the pop-ups somewhere off-screen, so when there's an incoming call, I have no way to answer it. So I wanted to disable the popup and get a regular window. I go to Options->Notifications, Incoming Call Ringing. The checkbox for "Display pop-up notification" is not clickable ('grayed' out). This occurs on other options, but not all - some do allow the pop-ups to be disabled. What gives? How can I turn this off?
I am using Linux Mint 13 Maya (based on xbuntu 12.04) I have the same problem. The display popup notification button is grayed out (Incoming ringing call) and the popup notification no longer shows up. There is a pop up notification clickable button for other notifications (eg contacts online and offline).
Same problem here with Skype 126.96.36.199 on Linux mint 13 (Maya). Incoming calls can be heard, but cannot be accepted or declined since the pop-up doesn't, well, pop-up. Neither can I uncheck the relevant box in options.
It's disheartening that the last reply dates from April...
