I just got a new computer at work. Normally I would go into an adjustment tool: Levels, Color Balance, and Hue/Saturation mostly; and could click on these guys and adjust them one number at a time with my mouse wheel. Now I can't do that anymore and I can't find anything within the Preferences menu to fix the problem.
This is also happening with other boxes, such as adjusting the feathering on the laso tool, adjusting the size of the eraser brush size, etc.
The old computer was a Windows XP and the new OS is Windows 7 Pro 64 bit. I doubt that would make a difference at all, but just in case.
Which version of photoshop were you using on windows xp and which version of photoshop are you using on windows 7?
When you say "adjustment tool" is that Image>Adjustments or adjustment layers?
I'm using CS5 on both computers, it was just transferred over.
Yes, I meant Image>Adjustments
