Magic Mouse erratic in Photoshop

Question

The magic mouse is acting crazy in Photoshop. I click and once my hand is off, the picture either minimizes to a dot or maximizes to gigantic pixelated size. So, for Photoshop I use a Microsoft Mouse and I have no problems.
I can't figure out why the MM is behaving like that. I doesn't happen in any other application, but then the Microsoft Intellimouse works perfectly.

Personally, and this is just my opinion and advice being stated here, but depending how much you use Photoshop and what you use Photoshop for, I would forget using Apple's Bluetooth  wireless mice (and, perhaps, forget their wireless trackpad, although I have been told its tracking is much better than the wireless Magic Or Mighty Mouse) and stick to using a third party wired mouse or wired trackpad or even older  IR remote wireless mice or trackpads as most IR wireless input devices track better and have better resolution.
I found Apple's Magic Mouse frustrating and terrible with all but more expensive higher grade batteries designed for high drain electronic devices.
And sometimes would not pair with my IMac or work erratically, too!
I return it within 14 days. I like the way it looked, but not how it worked.
I used to use IR wireless Microsoft and Logitech mice that tracked and worked real well.
I just, recently,purchase the Mac version of the Logitech Bluetooth Wireless trackpad and so far this works excellent with normal computer use, but haven't really tested using this for all my design and image editing apps, as yet.
I use a wired USB Wacom Intuous 3 drawing tablet with 3 brush pens and the high resolution mouse for all of my design apps.
Consider sticking to a wired input device or trying another third party input device.
