I just upgraded to FC5 x86_64. I installed perl-Tk-804.027-11.rhfc5.at. Unfortunately none of my perl-Tk scripts work any more. They all die with this error: 803ab0 is not a hash at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/Tk/MainWindow.pm line 55. Does anyone know what caused this? the scripts all worked fine when I had FC4 on my computer. Thanks. Derek Tattersall
