No idea.

However, I am just thinking about a workaround. You can use a Timer, to postpone your refresh code a certain interval, for instance, half a second. Form.Refresh() would have to call:

with ThisForm.TmrRefresh
  .Enabled = .T.
  .Reset()
endwith

And the Timer itself will include all the refresh logic. Note that if Refresh() fires 10 times in one second, each Timer.Reset() will restart the Timer - no form refresh will be done. Only if there is no Form.Refresh() during the specified interval will your refresh work be executed.

The actual commands to do the refresh might be in a form method which you create.

HTH,

Hilmar.
