Straighten tool in iPhoto to sensitive after update

Question

Since the last update (9.2.1)  of iphoto that was provided by apple my slider for the straighten tool is very sensitive. In the past I used to be able to make 0.1% adjustments.. now it's so sensitive I usually go directly from 0% to 0.6 or 0.8%..
I already tried a different mouse and adjusting the mouse speed.. but neither helps.. I never had this problem in the past. Anyone else has this problem? Or is there a way to make the slider adjust with the keyboard in 0.1 steps? I tried everything.. but nothing seems to help..

Answer 1

I just received an email notice of the two new posts on this subject; but no solution yet.  So I am rethinking the problem and what might be done.
The problem is, even on my big iMac, there are just two centimeters of slider space to adjust 45 degree's worth of tilt.  With 450 possibile points on the slider, they are just too close together. This is poor design by Apple.  What I would rather have is a method of entering a numeric value for the degree of tilt that I need; something commonly available with Apple's Inspector pane in other applications.
OR... the slider needs to be longer; and that was my hint.
Thinking about the lack of space to slide the slider, I tried something and it works!
First, with the screen displayed in the normal way, I get the tilt near to what I want.
Then, I use the control key and one finger swipe on the mouse to zoom in on the slider bar so that it fills my screen.  In this way, there is much greater control of the increments of degree change of the tilt.  It is still a bit touchy, but I can make changes in one tenth's of a degree.
Of couse, I need to zoom back out so that I can see the results, and possibly zoom back in to tweak the slider again.
Hope this helps.
