The "1" worked perfectly for me. Thanks for hunting this down for me. I appreciate it dearly...

I do not think it is a problem of LWP but Win32::GUI. because when I used to run very similar procedure as a CGI script under Apache web server, that is without Win32::GUI ,there were not such problems.

Right - that's my point. When you were running your CGI script through Apache, you weren't using Win32::GUI. Apache spawns your CGI script as a new process, so LWP can take as long as it wants without interfering with everything else. As soon as you run Win32::GUI, you've got to have one stream of consciousness listening to all the events happening in Windows. It has to listen to mouseclicks, focus events, window grabs, and all that crap. This is a constant "all the time" process. LWP, on the other hand, takes over totally. It becomes the "all the time" process the moment it runs. You can't (easily) have two "all the time" processes running at the same time, so LWP "wins" since it's the latest/newest one. With LWP being the "all the time", Win32::GUI can't listen to all the crap that's going on, so it doesn't know that it's supposed to refresh the screen or listen to your mouseclicks or so forth. It's not a problem with Win32::GUI or LWP really. Both are doing what they're supposed to do. And they conflict because of that. If you want your window to stop freezing, you have to figure out how to have Win32::GUI and LWP listen "all the time" at the same time.

[perl-win32-gui-users] Using GetOpenFileName
Hi I want to be able to show a dialog box with just a directory listing. Can I pass any parameters to the function GetOpenFileName to only show information relative to directories return the selected directory ? Or is there a different function that I need to use ? Many thanks, Piet
