Of course, if you're running it in MS win32, you should be aware that any "stay on top" windows (such as the taskbar and, on my computer anyway, Trillian) will still be in front. You'll have to do something using Win32 or Win32::API to move them to the back, probably. Although, it's possible Tk has some way to force a z-order for your window (I haven't checked).

Yeah - that's fine. I was going to put something in the help about how you could turn autohide on if you want to use fullscreen. At any rate, it's nice to have the option, for those that don't mind tweaking things a bit to use it.

This is what I ended up using and it works well, excluding the stay-on-top thing (tested on SuSE 8.0 (5.6.1) and Win98 (ActiveState-5.8.0):

if ($s->{fullscreen})
{
    $s->{fullscreen} = 0;
    $w->{main}->withdraw;
    $w->{main}->update;
    $w->{main}->overrideredirect(0);
    $w->{main}->geometry($s->{windowed}||"800x600+20+20");
    $w->{main}->deiconify;
    $w->{main}->update;
}
else
{
    $s->{fullscreen} = 1;
    $s->{windowed} = $w->{main}->geometry;
    $w->{main}->withdraw;
    $w->{main}->update;
    $w->{main}->overrideredirect(1);
    $w->{main}->geometry($w->{main}->screenwidth."x".$w->{main}->scree
+nheight."+0+0");
    $w->{main}->deiconify;
    $w->{main}->update;
}
