Mousewheel doesn't work after loading saved games.

Heyo,
I'm playing 1.6 and I noticed that when loading a saved game, either from the main menu or using the 'Revert to last save' button, the mousewheel no longer does anything. It works fine when starting a new game or restarting the level though. I have it set to cycle my presets.
Any thoughts or quick fixes that I could do?

When you loaded a saved game, did you redo your presets? I don't think saved games store that info, so you have to redo them.

The presets are there. I can use them with the alt+number combo or the f key. I tried resetting them but it doesn't help.
The zoom and move functions work if I set the wheel to them instead.

Does anyone else have this problem?
I really like being able to select groups without changing the view like with the f key. The alt combos are somewhat annoying too.
