Earlier this evening there were problems on the Facebook side. Many players were getting half screens and it was quite annoying. The obvious work around is to unframe your page but Zynga prevents us from easily unframing. A while back Team Spockholm created what Pistol Pete like to call fake unframing. To get your game into a fake unframed state and thus eliminate half screens, simply use the link below.
To learn more about the Spockholm Mafia Wars (un)framed page, click on the “About this page” link.
There is also a direct link to the Spockholm Fan Page and a convenient list of more helpful links. Stand alone scripts will not run on this page but if you use the Spockholm Mafia Toolbar, that won’t be a problem. For instructions on unframing workarounds, just use the link to the Unframing Guide.
During the half screen issue, Zynga was on top of it and posted the following on their Customer Support Page. In addition of half screens, there were also issues with the request buttons. Everything should be back to normal now. This was a Facebook and not a Zynga issue.
