I have a installation of Revit 2012 (64bit win7) that some times stops drawing dialogs and Revit menu (the big R-button) in front (or something). If I press open, the dialog only pops up if I press somewhere in the revit window, and windows plays that DING-sound (like when you do something you shouldn't do). It feels like a menu draw issue.. The R-button just never displays a menu when I press it.
A restart of Revit fixes the problem, but its annoying and we all know Revit doesn't start very quick...
you could check the following points if you have this issue:
1. You may reset the Quick Access Toolbars' settings to the default one by deleting the UIState.dat file.
Please find some more details in the following technote:
2. You may check the memory conditions of your computer; enough ram, please regularily delete the content of the windows temp folder (you can open the Temp folder by entering %TEMP% in the Address bar of Windows Explorer).
3. You may check the video card+ driver on your computer. Please make sure you are using a certified card+ driver. If there is no test result about the appropriate card, then you may try to use the newest available driver.
