Zoran, what I suggested works on most. The Parent and Owner are important, because if the owner is the mainform the extra dialog gets hidden, but if the owner is the modal form, the dialog is shown on top of that, bypassing the mainform. You have to do that in code, including the dialog creation.
Of course the national anthem of the U.S.A. was written by Jimi Hendrix, didn't you know that?

I don't have relevant system to test at the moment, but I remember that setting PopupParent property of the form-to-be-shown to the currently shown modal form, together with PopupMode set to pmExplicit helped sometimes. These properties should be set before the form is shown.
Even that could not help in some window managers.

So, I think that what you mention as the Owner here is not the Owner property (from component creation system), but the form to which PopupParent is set. I might be wrong though.

Thank you, Zoran!
I changed the test project (show non-modal forms) - added the choice of StayOnTop or PopupMode. StayOnTop works more reliably on XFCE:xfwm4.
Can someone check it out on other Linux configurations? I am interested in whether it is possible to hide the dialog under the form so that it does not go up, on whatever form you click.

Superficially, that's OK on Debian 12 with KDE compiled with the defaults (GTK2?).

Don't have XFCE etc. conveniently to hand.

I think I might have come across an interesting example of this sort of problem in the Lazarus v2 IDE itself, at least under Linux+KDE+X11.

If you're running a program (waiting for any exceptions etc.) using the IDE you can edit the sourcecode without problems.

If you try to create a TODO however you appear to get locked into the (modal) TODO editor, with no alternative but to kill the IDE hence lose your debugging session.

I won't raise it as an issue until I've checked the current version.
