simple 3d view problem


i am not that familiar with Blender so this is probebly a simple problem.

i am using blender alpha 2.52(i think) and the problem is that the speed of my 3d view rotation have increased alot and it’s hard to do precise work.
when i say 3d view rotation i mean when i use my MMB to rotate the view.
any ways it is accelerated and i would like it to be back to normal speed.

i must have touch a button by accident or something like that

sorry for spelling/grammars and a thank you in before!
if you need more information just ask.

Try File / Restore Factory Defaults or check your mouse properties, however you do that for your operating system, to check the sensitivity
The latest official 2.5 version from is blender 2.53beta
