I'm running Windows 7 Professional 64-bit on a 64-bit machine. With some applications when I double-click a file in Windows Explorer or open it as an email attachment the application loads, but the file does not load once that application is open. I cannot drag and drop the file from Windows Explorer into the open application either. I am forced to use the File --> Open dialog. I did not have the same problem with these same applications on m Windows XP Professional SP3 32-bit machine.
I have set the EXEs on all of the applications I'm having this problem with to run as administrator and that does not help. It is happening with Visual Stduio 10 and PL/SQL Developer, but it isn't happen with Microsoft Office. Does anyone know how to fix this?
