Comment 13 for bug 1306550

Correction for my comment (#12):

This statement was wrong:
"For instance, after this problem appears, I can no longer click on "Open new tab" button in Firefox (it opens the Clock/Calendar indicator instead if I have more tabs open in Firefox and the "Open new tab" button is bellow the clock indicator)."

The corrected statement:
When this bug appears, the registered click is somewhere bellow and to the right, compared to the displayed mouse cursor position (not above, like I said in my previous comment).

So , if I want to click on something, I must place the mouse above and to the left of the intended mouse click target.
