    Yep, A reference allows you to pass the actual variable (contents and all, which is what you need) With the single quotes, you're basically passing an indirect reference (though not quite in the way that more or less works) and that's generally considered a Bad Thing. Try passing a real refernce as I mentioned in my last post, and let us know how/if that works.

    I believe the sub will need altered a touch to, this should do it:

    sub quit {
    $$_[0]->destroy;
}

      Alright, I've messed around with it a bit, and managed to get it down to this: 
      MainWindow=HASH(0x164a81c) is not a widget at *.pl line **.

      Any more ideas?

        What is $windowname? Where does it come from/get created? Can you show the code that creates it? Also the result of ref($windowname) which should tell us what it is (widget or no).

        I suspect it's getting unblessed somewheres..
