I would try taking the wait windows outside the case statement and see what happens. Try this, and see if it's all keys that stop previewing, or just the particular ones your trapping for. Perhaps the case isn't being met for some reason?

>>Works just fine for me. It returns 1, and 6 just as Marc said. Do you perhaps have an OKL defined for these keys?

>>>I have KEYPREVIEW = .T. and I can capture various keys like PGUP, PGDN, CTL_HOME, etc...

>>>But when I press HOME or END, nothing happens... I've placed a WAIT WINDOW in the KEYPRESS event to verify this...

>>>Do I need to use ON KEY LABEL to capture HOME and END???? Why????
