Comment 2 for bug 167781

Solution that I found is in ui/widget/selected-style.cpp on or around line 1150 (SVN revision 18485) to remove the defocus for the opacity spin box and it fixes the problem listed in the bug report.

In the comment above this code it says that there is a fix there for display interruptibility and the value-changed event being fired off repeatedly and causing the spin box to runaway in it's spinning till it hits 1.0 or 0.0.

I was unable to make this box uncontrollably scroll with my fix in place and was able to press and/or hold the up and down arrow keys to change the opacity without moving the object.

Attached is the diff on ui/widget/selected-style.cpp
