Launching Bible+ 3.2.0 on a Palm Vx with OS 3.5.3 and
at least one bible module present in RAM causes a fatal
error "SystemMgr.c, Line:154, Unimplemented" and the
need for a soft reset.
POSE displays the error message: "Bible+ (3.2.0) called
Palm OS routine #0xA348 (FileSystemDispatch). This
routine does not exist in this version of the Palm OS."
The bug is present since around 3.1.37 RC3; version
3.1.30 beta does not have it.
Quick guess: The bug may be related to not checking the
OS version or VFS presence before using a VFS function.
