Sorry I can't give you a remedy, but I can confirm the problem and that 
no one has come up with a fix. 
I presume your 'wireless mouse' is Apple's Magic Mouse. The jumpy 
behavior is common in all Adobe apps as well as others such as 
NeoOffice. I posted this question to Macintouch on May 19, 2011, and got 
zero replies.

I'm also very frustrated with the Magic Mouse. Inadvertent scrolling is 
rampant with my hand position...

I think some of the problem with inadvertent scrolling is the fault of 
software. I find large variation in how an app reacts to scrolling. 
InDesign seems the worst to me. I often launch an object out of the 
window while clicking.

To expand on Stephen Hart's comments about Magic Mouse scrolling 
inconsistencies, I have found wildly different scrolling speeds and 
reactions depending on specific applications and situations. My wife 
can't use MM with any Adobe products. I have found I have to be 
extremely careful with NeoOffice. I have even noticed the variability 
_within_ a sub-window in a Safari web page where scrolling in the parent 
window is normal. While I grudgingly admit to possible user error, these 
circumstances are entirely reproducible.
Perhaps there is someone familiar with the sensor hardware and its 
controlling software who could explain this app-to-app variability for 
us.

Presumably the OS is gathering and feeding the same mouse tracking input 
to each app, so why do apps behave differently? And none of these apps 
have custom mouse-tracking prefs that I know off.
Input from knowledgeable hardware experts eagerly solicited!
