There seems to be a bug or incompatibility between TGL and win32:GUI.
If you create a new TGL window and add a HyperLink control and then try to preview it, you'll see what I mean.
The error is "Can't locate auto/AddHyperLin.al in @INC(...."
I have managed a small change to the HyperLink.pm modules to get my code to work, but I cannot get the TGL preview feature to work.
I am using .22 version of TGL, ActiveState perl 5.8.3 and Win32-GUI .671
This has been happening for a while. I kept hoping the next release of something would fix it.
Why Wait? Move to EarthLink.
