Hi JRL,
Shocking! Your code works fine, regardless of .bmp sizes and folders (%Desktop%\, or C:\Temp\).

Would you please suffix the Help's window title with one magic word "Help", namely, "Macro Scheduler Help"? Thank you. Got to ask - what earthly reason ...

Almost all help files available in the universe are suffixed with "Help".
