Hey everyone - I have a question. I was just able to finally purchase a new iMac and am in the process of switching everything over from my Dell. On my pc, I had purchased third party software to size my brush up and down in Photoshop using my mouse wheel. Does anyone know if there is anything similar for the iMac and magic mouse? I downloaded one last night (the name escapes me), but it was not compatible with the magic mouse.

Any suggestions??
