Red Timer opens on wrong display.

[Kain-Ash]

I have 3 displays on laptop.
When I have 3 displays connected on laptop Red Timer opens OK on one display when I click on icon in task bar, near clock.

But then I hide red timer again, (close window).
Unplug 2 monitors, and click red timer again, (or right click Show/Hide) and Red timer is shown in task bar, but form is missing on screen.
Could you fix program, that when you show Red Timer form, that you check which displays are valid and then show red timer on valid display?
(I think that in config of Red Timer is written, show form on display 3 and on show command you show Red Timer form on display 3 even if that display is invalid/inactive.)
