Thank you all for your answers I did like this:
my $mythread = new Thread \&MainEntry::StartProcessing;

It looks at it was sufficient to solve the problem. Im not sure if the thread is alive after it has finished the StartProcessing sub however..I have tried to $mythread->detach; but it gives me a the error:

"Attempt to free non-existent shared string '_TK_RESULT_', Perl interpreter: 0x1f28444 at C:/Perl/site/lib/Tk/Widget.pm line 98 during global destruction. Free to wrong pool 1f273d8 not 223f90 at C:/Perl/site/lib/Tk/Widget.pm line 98 during global destruction. "

Does anyone have a clue what the problem might be?
