Don't you need

Code: Select all

#PB_Canvas_Keyboard

for keyboard stuff?

What if he's changing the focus to another gadget by clicking with the mouse?

Maybe it should, but that's not the point.
The point is that in Mac OS, an infinite loop starts, whereas in Windows, there is no such thing.

My problem is visible immediately after compiling the code.

seems like SetActiveGadget( -1 ) ALWAYS triggers lost focus

Code: Select all

Procedure lostfocus( )
  Debug "lostfocus"
  ;SetActiveGadget( -1 )
EndProcedure
