Dear Monks

I have TK window with two drop down fields. The Idea is that if users specify parameters for thoes drop down fields, or else the script will pick up the data specified in __DATA__. the script works ok the first time its run. Problem is, the seek (DATA ,0 ,0);seems to do a strange thing! I get a bit of the code dumped on the screen too when its called for the second time! instead of the seek()command rewinding to the top of the __DATA__! its rewinding half way up the actual code instead!!!

I have never came across this kind of behaviour where chunks of the actual code gets dumped on the screen!!

Can somewone please enlighten me why is this happening? And the way around it?

Thanks.
