I do not know what happened, but Aperture 3 was working fine until I did the Snow Leopard 10.6.4 update. All of the sudden the mouse became wild, jumping randomly all over my two screen (I use the magic mouse but I also tested a regular mice).. Also, the slider have become unresponsive to the point that I cannot do any work.
Thinking that it may have been a corruption during the upgrade I then downloaded the Como update but experienced the same problem.
I then decided to do a clean install of Snow leopard and every program, and after 7 hrs installing everything, I got exactly the same problem.
I am about to give up on aperture. Has anyone experienced the same problem? Any problems?
I am not blaming anyone or anything, just describing my problem and looking for solution.
Which Mouse? I tried three now. I tried different surfaces. And just in case... I cleaned it too. (How do you clean a new magic mouse that has no issues except with Aperture?...)
Plus, as I said, the only program doing that is Aperture. So, by process of elimination it is Aperture.
And, as I said, it only happened after the 10.6.4 update. before that it worked just fine.
Also, the mouse was re-paied as I reinstalled everything from scratch...
I also checked the setting but setting wont cause the mouse jump to the extreme left while moving the mouse to the right. Surface may, so that is why I tried different one.
I really appreciate you guys trying to help, I really do, but please, please, read before writing as you will see that everything suggested was done.
Could you please check your settings in System preferences->Universal Access->Mouse and uncheck "Enable access for assistive devices" at the bottom of the panel. What is the relationship? Sorry, not in mood to explain, but it is known to cause problems you describe.
