I'm running PD9 here on Mavericks and I mainly use Visual Studio 2013. Constantly it seems like PD is getting incorrect keyboard input. Suddenly Visual Studio changes to a new file or the Windows start menu opens.
For instance: it looks like it is missing to catch key combinations like ALT+Page Down, instead does Page Down only and then connect the ALT modifier to the next pressed key, which will trigger a different actions.
Any ideas what could be causing this?
