[Wine] Paradox 16 bit crashes with page fault

[the_nipper]

Hi!

I was able to install my good old Paradox 5, a 16-bit application.  But when I start it, it crashes after some (correct) Dialogboxes with that trace:

> wine 'C:\Programme\PDOXWIN\PDOXWIN.EXE'
wine: Unhandled page fault on read access to 0xffffffff at address 0x11f7:0x00000f02 (thread 0018), starting debugger...
Unhandled exception: page fault on read access to 0xffffffff in 16-bit code (11f7:0f02).
fixme:dbghelp:addr_to_linear Failed to linearize address 0111:0000ef00 (mode 0)
In 16 bit mode.

Register dump:
[SNIP]

It's Wine 1.1 (and 1.0 did the same).  Is there any general problem with old 16-bit stuff?  Any known patch?  There's a detailed fixme hint!?

Best,

Robert
