Comment 10 for bug 1012257

I can reproduce it fairly consistently in the old blogger post-edition interface: all I have to do is to select a block of text, click the "insert link" button, and then try to scroll with the mouse wheel.

The last X event that xev reports when the mouse cursor is turned into a grabbing hand is:

LeaveNotify event, serial 19, synthetic NO, window 0x8400089,
    root 0x10f, subw 0x8400104, time 3973343933, (323,396), root:(851,448),
    mode NotifyGrab, detail NotifyNonlinearVirtual, same_screen YES,
    focus NO, state 16

HTH.
