I'm in shock.
I used to work in VB6 all day every day and be happy, but then came Visual Studio and I was spoiled, I was corrupted, I expected more. That one line bugfix in the legacy code was a nightmare and all because the mouse wheel didn't work.
Now I am very keyboard intensive, but when you spend a huge time trying to read code (I said it was old) then it's easier just to roll up and down. But nothing happened. So I can only praise to the poor individual at MicroSoft who it has obviously driven mad, and he/she has spent time fixing it.

Mouse wheel events do not work in the Visual Basic 6.0 IDE
