Hyper-V Program Manager
I guess I'll start with why I love drag and drop in Virtual PC. Firstly - Virtual PC is the most drag and drop friendly application I know.
So why do I hate drag and drop in Virtual PC?
Simple - it was originally implemented on Virtual PC for Macintosh - where most people only have one mouse button. As a result - drag and drop on Virtual PC (for Windows) only works if you use the left mouse button.
Now - my background in operating systems is actually very OS/2 heavy - and on OS/2 you can only drag and drop with the right mouse button. In Windows you can drag and drop with the right mouse button with no problems - but not in Virtual PC.
Drives me crazy...
The other reason why I hate it is that it generates the most cryptic error messages: 'An error has occurred during a drag and drop error (d3)'
I don't even know what that means. We should really fix that.
