Alright! Thanks, however, seems like I missed something "important". The thread is actually the GUI part...

my $GuiThread  = threads->create("startSystray");

sub startSystray {

    $mw_win32 = new Win32::GUI::Window(
    -width   => 0,
    -height  => 0,
    -name    => 'MainWindow');

    $systray_menu = new Win32::GUI::Menu(
           "SystrayMenu Functions" => "SystrayMenu",
           "> Info"      => "SystrayInfo",
           "> Exit"      => "SystrayExit"
    );

    new Win32::GUI::NotifyIcon($mw_win32,
    -name => "SysTray",
    -id => 1,
    -icon => $icon);

    my $call = Win32::GUI::Dialog();


}


sub SystrayInfo_Click {

#    my $A = new Win32::GUI::AcceleratorTable(
#        #"Ctrl-X"       => "Close",
#        "Shift-N"      => "New",
#        #"Ctrl-Alt-Del" => "Reboot",
#        "Shift-A"      => sub { print "Hello\n"; },
#    );
    $infoWindow  = new Win32::GUI::Window (
                                    $mw_win32,
                                    -width => 400,
                                    -height => 200,
                                    -left   => 300,
                                    -top    => 400,
                                    -name => "infoWindow",
#                                    -accel => \$A
                                    );

    my $text = join "\n", @actionHistory;

    $richEdit = new Win32::GUI::RichEdit (
                                    ...
                                    );
}

That is, the GUI is a thread on its own. Not sure how to solve this, and in a good way. I can't really send the $richEdit to the _Click() function... Not that I know of anyway. (That's one of the reasons I have the richedit as global...) Thing is, the $richEdit is not defined for thread 1 (the noneGUI thread) for starters. Its only defined when user klicks in tray. So, I cant pass like that either it seems... Hmm...

Edit: Maybe Im gonna create the GUI, and hide it. Only show when klicking in tray...
