I find it a bit embarrassing to report back here, but unfortunately I've encountered another problem.
The icon for VS X4 has become corrupted and is now showing the default (?) icon in the taskbar and start menu. It may be worth to note that I can still see the original icon in my ObjectDock dock. I also use CCleaner and wonder if it may be a contributing factor to the icon becoming corrupted so I have excluded X4's program folder in its settings.
I'm running Windows 7 64 bit on Dell a XPS 420. If I need to give more info, please let me know...
