Greetings Nestor,
Odd, I also have the same problem here. It does move fast. One time, It move so fast, the minutes hand counts every second too fast. The problem is quite intermittent from time to time. Although It does not affect the Emulation as whole, I suggest restarting it(the software itself, not the Amiga Emulation) should fix it for now. I have not tried the lastest version (0.9.??) yet. I'm using (beta 1) 0.8.25 from Amiga Forever CD.
Regards,
Gizz
