>I am trying to load an ActiveX control using 'Tools/Options/Controls/Add'. When I try to add the control I receive an error message "File 'P:\New Fox\TabletTest\LoadTiff.ocx' does not exist". My brain does not seem to be functioning correctly today. What am I missing?

It sounds like ActiveX LoadTiff.ocx has been either deleted or moved after it was registered. Did you check that 'P:\New Fox\TabletTest\LoadTiff.ocx' exists?
