Hi Monks-

Here is a strange problem. The perl application listed below works fine for me, with the supplied data under windows XP (32-bit) with activestate perl 5.8.7. However, if I build an executable using perlapp, and run it on the same data, windows reports that the program stops responding, and I can't scroll, nor will the stop button work).

In addition, using poe_main_window doesn't work (see where I commented "WHY DO I HAVE TO DO THIS?").

If I take the JSON stuff out, the scrolling & stop button work, and it seems to run ok.

Any thoughts or help is much appreciated!

Thanks

-Craig

Here is the perlapp command line: 

perlapp --add "POE::Wheel" --add "POE::Loop::Select" --add "POE::Resou
+rce::Aliases" --add "POE::Resource::Events" --add "POE::Resource::Ext
+refs" --add "POE::Resource::FileHandles" --add "POE::Resource::SIDs" 
+--add "POE::Resource::Sessions" --add "POE::Resource::Signals" --add 
+"POE::Resource::Statistics" --verbose --clean --force --lib lib --exe
+ analyze.exe display.pl

Here is the data for the input file: 

{"Text":["Hi there...","How are you?","1","2","3","4","5","6","7","8",
+"9","10","11","12","13","14","15","16","17","18","19","20","21","22",
+"23","24","24","26","27","28","29"]}
