Thanks for the analysis, Duane.

It turns out that the issue is in Microsoft's MFC code, in a function called 
AfxLoadSysColorBitmap(). This function is part of the CToolbar class 
(bartool.cpp). It does a couple of weird things and seems hard-coded for 
16-color configurations.

The developer for PocketFMS changed the reference to this code so it gets 
called in 16-color mode and now it continues past this point. The next 
hurdle is a problem with file creation, which fails on the following:
0009:Call kernel32.CreateFileA(00b29480 "c:\\Program 
Files\\PocketFMS\\\\bdryhV6.gpsdat",80000000,00000003,0033ec30,00000003,00000080,00000000)
ret=0055679a
0009:Ret  kernel32.CreateFileA() retval=ffffffff ret=0055679a

Looks like the double backslash between the path and the filename make Wine 
barf. I thnk it's OK to do this in XP though, at least that's what I recall 
from previous projects.
