Thanks very much thundergnat... I have 800.024 for your perl -MTk -e "print $Tk::VERSION" command... Your script too is working, I can colour the window from the chooseColor thingy, and all are coloured. I'll have to take some time to get my head around it though. O... just to say the first time the window pops up it is still not all coloured but after the selection from the chooseColor thingy things are fine... No need to reply again... Thanks much...
