Here's a strange one.

A menu item which calls a help file from within a do loop as one of the CASE options does not return to the place it was called from.

For example, if a beep() is put in the CASE Help: option after the call to showhelp(), but before the break; then the beep sounds as soon as the help file is opened. Not as you might expect when the OK is activated to close the Help file?

e.g. do loop etc...

CASE Help:
showhelp()
beep()
break;

it's normal. Showhelp just tells the system to call the help program. Your app isn't stopped and the beed is heard just after the help is shown

OK Thanks,

but now the obvious question:

How do you make it stop there until OK is pressed before sounding the beep e.g.?

I think you could just wait for an event.
When the helpis closed. the main window needs to be repainted. So you get a PM_PAINT event. But when you swich from the taskbar ( or any other task manager ), or you move the help window (on HPC's), the PM_PAINT will be sent too. So manage how you fell it. you can't figure out if the help window is ot isn't closed. You can write "tap on the screen or press any key to continue" on the screen and wait for one of this event.

OK Thanks Justin

I found that including a dummy case for PM_PAINT sent it through the loop again and solved the problem.

In other words, including the line

case PM_PAINT:
break;

Worked fine
