Hi!

Take a look to the GetWindowInfo API function in the MSDN help. You can call it from VFP. The structure it returns contains the dwWindowStatus flag. Following is from the help:

"The window status. If this member is WS_ACTIVECAPTION, the window is active. Otherwise, this member is zero. "

Than you can check in the timer event if the window is active to see if refreshing is required.

If you just looking for the minimized state of window, just check if _Screen.WindowState=1 in the timer event.

HTH.
