>Adding a timer object to forms is pretty straightforward. However, I'd like to have a timer object for my entire application, which I assume needs to be instantiated at the _SCREEN level. How do I do this? When I do a search within VFP 6's help, the screen which shows up doesn't help me at all.

Try just like on a form at desing time, use the AddObject() or NewObject() methods (not funcitons)
