I'm currently using the code above to setup clickcast on raidframes.
But the "self:ClearBindings();" seems like not functioning well lately.
Do mousewheel would bind to a random raid unit button, and override my mousewheel camera zooming.
The only solution is an UI reload.
Anything I can do to avoid this?
