Update: This is actually a Windows 'Feature' interacting with a Foxpro 'Function'. To correct, edit the properties of your icon or window, select the Misc Tab, and set the Idle Sensitivity slider to 'just about' Low or Low. For information on this setting, click the '?' upper right and then click the slider. This tells the window the priority to allocate CPU cycles for Keyboard Input. Set too High and INKEY(1) (in background) will never timeout.
