Par2: Windows reserved keys 2000-10-31 -- Ralph Johnston >Has anyone ever had this problem:
>
>I placed keys F1 to F10 on 10 buttons. When the F10 button is disabled and
I press on it, it freezes the use of the 9 other button (F1 to F9).
>
>After some tests, I've noticed that the F10 reacts like the Alt button in that sense
that if I press the 'F' key after having pressed F10, I go to the file menu of my
application. But if I press F10 twice, everything is normal and I can use F1 to F9
as if nothing happened!
This is a less-than-well-documented behavior of Windows. To
paraphrase the Windows Design Book (The Windows Interface: An
Application Design Guide), these are some of the function key
assignments: F1 = Help, F6 = Move to next pane of active window, F8 =
Toggle Extend Mode, if supported, F10 = Toggle menu bar activation.
There are others, like Ctrl-F4 and Alt-F4.
Anyways, what is happening is that your menu bar *is* being activated,
but due to the Win '95 style menu bars, you can't *tell* that they
have been activated. The solution? Don't press F10!
Note, I think that it is Windows that is grabbing the F10 key, not
Clarion, but I'm not totally sure about that.
