Chris:
I'm using generic Codebook 6.0. Also checked and the libraries being looked for are not excluded from the build. I wonder if application size has anything to do with it - the EXE is <7 MB.

Mike:
I tried your idea, but with the empty directory structure I still get the same thing.

I recompiled all libraries and tried again - still the same thing. I'm gonna dig into the particular method and see if anything's funky there.

Does this smell like the old FPW 2.6 deal where if you had a CD ROM drive mapped as D:, you'd get an I/O error unless there was a CD in it?

Thanks for your input.
