You have to show the code, and be aware that Perl5.61 is ancient, and that Windows presents some problems, so we can't say what is happening just based on your question.

In general, you can do a $mw->update often to keep the gui responsive, but I'm inclined to believe that you are running into an odd problem because you are running on Windows, or the command you are executing is very fickle. See How to skip to next Command line
