I've ran into something odd that I can't seem to find a remedy for. I recently installed Xamarin Studio 4.0.8 on OS X 10.8.3 and had installed the MonoFramework MRE (prior to Xamarin). Everything was going fine, however I realized I needed the Mono Framework MDK for building another project. Without thinking about it, I installed the MDK over the MRE, and upon opening up Xamarin studio the File/View/etc. menus were gone and I cant seem to get them back. I've tried removing Xamarin Studio and the Mono Framework completely and re-installing them.
I'm new to the Mac, so maybe there's a cache somewhere that I could remove to reset the toolbar, but any help that I can get would be appreciated. The attached file shows what I mean (I'm not in full screen mode, the File menu is just completely gone!), opening a solution doesn't help. This is only a problem for Xamarin Studio, all other applications are acting normally.
