I recall seeing inventory management systems, airline booking apps for travel agents, custom CRMs, internal LoB apps, check-in kiosks, vending machines, etc. with the tell-tale VB UI, especially the typical VB error dialog after a crash!
I messed around with several other UI toolkits of that era -- AWT, Swing, Qt, Flex/ActionScript -- and none was as productive as VB for simple apps. It was just the right amount of simplicity and development velocity for the myriad simple use-cases that were perfectly happy with rigid layouts.
