Hi,

Thank for your advise on the doevent().
By the way, is the Vfp 5 wait command timing accurate ? Or do I
had to use Win32Api insteads ?

Plus, having doevent() once every few hundred iterations of my
processing loop actually prevent my user from action like stoping/exiting
using the mouse/keyboard on my application. Is this problem cause by bad design, please advise me on this. Thank you.
