I've prepared a LyX-package with Qt-4.8.0 and the upload is here: http://dl.dropbox.com/u/27842660/LyX-2.1.0svn%2Bqt4.8.0-cocoa.dmg http://dl.dropbox.com/u/27842660/LyX-2.1.0svn%2Bqt4.8.0-cocoa.dmg.sig The Qt 4.8.0 ChangeLog contains this: Qt for Mac OS X --------------- - Alien widgets is now used by default for Qt/Cocoa on Mac OS X. - Qt/Cocoa on Mac OS X has now full support for the raster paint engine. - QApplication has now implemented macEventFilter for Qt/Cocoa - HarfBuzz can now be used as an optional text layout engine on Mac OS X. [QTBUG-17728] - Qt shows some love to OS X Lion (10.7). Perhaps this is an improvement on Lion? Please, can someone give it a try? Stephan
