Well, yes, that's what I've been doing ... and then the message box comes and won't allow the installation/running the program. There might be more I could do if I wasn't operating with Vista (but then, I wouldn't have the problem in the first place).
I've just looked into alternate interface programs ... JavaFibs isn't for me, but DelFibs appears comparable to FIBS/W, sans some of the convenience buttons.
Want to thank you just the same for trying to help me out!

I'd still rather run FIBS/W, and will hope someone else pops along with a fix for me!
