The same problem.
I made a screenshot that almost exactly shows what I mean.
Note the one gmrun application visible and its corresponding launcher icon with the question mark, note how many gmrun running shows ps aux |grep gmrun.
The cursor had the shape of input feald when it was above (there is where the invisible gmrun window was), I do not know why it shows in its normal shape on the screenshot. I have tried to make it 3 times, but allways with the same results.
