Under Windows 2000 service pack 2 and biprocessor system

if I use

SetTimer(hWnd,IDC_TIMER1,50,NULL); // Post WM_TIMER to main Window

it work. Instead if I use

SetTimer(hWnd,IDC_TIMER1,50,TimerProc); // Call TimerProc callback

when the user interact with the program it work and freeze when the program
run without interaction.

(The Timer update status bar with system date/time and I see that the
seconds stop updating)

On uniprocessor systems all OK.

Is this behaviour already known ? Is it a feature (Not a bug ;-) ?

Thanks for answer...
