How to debug the program with PauseForUser function?

Hello!

I have to modify the complicated interface which uses PauseForUser, and as I use the debugger to read the program I can't do anything because this function is blocking everything except the action on the panel. I would expect that if I click on the panel the action would take place and I can continue the debug. But this is not happening.

If I set the breakpoint after this function, everything is fine - I do my action, then arrive at the breakpoint.
If I set the breakpoint before this function, and then try to advance, then arriving to this line I can't click on the graph window, and I can't do the next step.
Even if I If I set the breakpoint before and after this function, debug the program until several lines before, then press "run", the debugger does not arrive to the next breakpoint - it stops on PauseForUser and does not let me do the required action.

If it is of any help, the function is called like that:
PauseForUser WMImageThresholdGraph,$NameOfWave(Ch0ThreshPic)


Thank you in advance!
Running the debugger while calling PauseForUser is problematic. As you know, PauseForUser allows interaction only with the main window and target window. The debugger is another window that needs to allow interaction. We have some special code to allow the debugger to work with PauseForUser, but I'm not surprised that it doesn't work well.

I'm afraid the best way to debug problems with PauseForUser is to fall back on old-fashioned techniques: print out values from the code that runs during PauseForUser.

You have a targetWindow that has the same name as a wave?
