Maybe I didn't understand your problem... But it seems to me that you are not using a real timer. I don't see why do you need an DO WHILE. I thing that if you have a timer, all you need to do is:

YourTimer.Enabled=.t.
when you start the SQL and
YourTimer.Enabled=.f.
when it is finished.
Of course, YourTimer.Timer() must contain:
wait wind 'Still Going...'+time() nowait
