I finally need to use tabstrips for one of my programs and decided to look back over some discussion that went on about them. To get a feel for how they work I tried running Eric Hansen's tabstrip sample from 2/18/2000 but got the following message: Your vendor has not defined Win32::GUI macro AddLabel, used at tabsamp.pl line 52. at C:\Perl\lib/Win32/GUI.pm line 361. Why is this error occuring?
