I was doing some stuff with GUI LOFT a year or two ago. I also found it very useful but I ran into bugs (not unlike yours as I recall) that I couldn't get resolved and couldn't get any help on. I had the impression that the developer lost interest or got busy with other things.

I wound up just going to Perl Tk. You might save yourself a lot of time and frustration by doing the same. It's not nearly as straightforward but it's more reliable and you can find support when you need it.

Or if you're really brave, you can wade into Win32::GUI.

Good Luck....Steve
