Below is correct.

>You need to set the public variable in some more places then just the init event. If you open another window and then switches back your variable will point to the last opened window and not the window you actually standing in. I have put the following code in the GotFocus and Load Method and it works good for me.

>if not empty(This.HelpContextID)
> gnHelpContextID = This.HelpContextID
>endif
>
>In the Unload event I also put: gnHelpContextID = 0 to make sure I don't get help for window thats not open.
