--- Comment #6 from Jim JSladek@juno.com --- According to PCLinuxOS software testing, FPW failed in releases 4.12, 5.0.5, 6.0, 6.0.1 & 6.16 - the common problem being that 16-bit support was dropped above release 4.0.4
That appears to be the answer to the problem. It's not a bug, but a wine configuration decision.
