So many issues with photoshop

Hi i would like to know if im the only one experiencing these issues in photoshop, it seems like at every turn i have to make some sort of loophole to go around the problem.

1. flick paning freezes the canvas and i cant do anything but save and close again.
- Solution. Open a new window at Window > Arange > New Window for... changed the shortcut to Ctrl+W.
I dont want to turn off flick paning it just feels weird.

2. I installed a brush, now icant use the brush tool properly, everytime i select the bursh tool the selection automatically switches to zoom.
- Solution. Hold down the shortcut for Brush everytime i use it which is all the time. its annoying.

3. the most recent version of photoshop, i cant use my wacom tablet. 
- i had to downgrade to an older version that seems to have solved the problem.

I jumped from cs 9 to the new version, in CS 9 i didnt have any of these issues photoshop ran great i never should have removed it.
