I'm using FontLab Studio 5 for Windows XP and I keep running into some very frustrating behavior.

After importing all of my glyphs, I've created metrics classes and assigned metrics to my font. I then begin creating classes for kerning and, a few minutes into the process, will flip back to my metrics classes to find them all suddenly gone.

At the very least, thank god, the metrics are still there for each character, so the work isn't 100% lost, but the class-based organization of all that work appears to be gone.

This is just one of many, many frustrations I have with this program, and while it's functionality in the basic sense is impressive, the interface and general finesse of the program is mind-bogglingly incomplete and unstable. That, combined with the fact that it doesn't appear to come with any help or documentation whatsoever aside from a superficial, semi-incomplete and poorly written manual, is really making me wonder if the price tag is totally justified.

Phew. Just had to vent about that a little.

But back to the issue at hand, has anyone else have this problem? I admit I could just be doing something wrong or missing something obvious, but the shoddy documentation isn't helping me zero in on the cause.

Thanks!
