I'm having an odd issue with the mouse wheel interacting with the middle mouse button.
How it normally works with my setup:
Lbutton + Rbutton = forward
Middle button (pushing down on the wheel) = target next enemy
Rbutton = move the camera
This allows me to move the camera and target the next enemy with the mouse at the same time.
However, if I use the mouse wheel to zoom in/out, right button + middle button is now forward, as is left button + middle button. I lose the functionality of the middle button while holding down Rbutton.
If I use the mouse wheel to zoom in/out once more, things go back to normal and I can once again pan the camera while targeting with the middle mouse button.
I am using a new cheap mouse as my previous one wore out, so I'm sure that's the cause. I've uninstalled/reinstalled the mouse, checked for updated drivers (there are none), move keybinds around, checked a dozen different characters. Whatever function I've assigned to middle mouse button doesn't matter, rolling the wheel once changes my ability to use the middle + right mouse buttons and rolling the wheel again restores it.
What the hell?
Edit: I don't know offhand of any other programs I could check this specific use of middle + right mouse buttons, so I can't tell if this is only applying to city of heroes or if it's an operating system problem
