Comment 2 for bug 777133

I add this comment because I beleive it's related.

Whenever I download a brand new built from modevia, I just unpack it over the old version. I now have Inkscape 0.48+devel r10207. OS = XP sp2 32bit.

I just ran into the same issue again. The arrow key didn't move any objects. I tried several type objects.

Then I found a way to solve the problem. I could still move objects with arrow keys IF I held either Alt, or Alt+Shift down (and possible also just the Shift key).
After doing this for a while, the arrow keys was suddenly capable to move an object when only the arrow keys was pressed down.

I'm sorry to say, I haven't found a way to reproduce the issue. My theory is that it happend when using a newer version, but settings stored in windows was stored from an older version.

Also, I didn't try to delete the program settings folder in windows. That might also have solved the problem, But unfortunately I never tested that out.
