-Do a SetFunction on OpenWindow(), OpenWindowTag(), ...
-Test if the window opens outsize your looking area
-If not replace it inside!
To know your looking area you can take help from this piece of code.
You can use this code into your programs (commercial or not) but I do
not give you the right to have money from this only code. I am the
only person who may send this listing to a magazin, a net, or write it
into a book.
I hope that future applications (even WBench :) will be user-friendly
enough so that they will not open outside the looking area.
Yes, there is too many things to take care with the new system, or that
we have to do ourself (be careful with the WBench font height, that does
often bad things with applications menus).
