wine users - May 2005 - Failure at "request for second install disk"

I've been trying to install a CAD program called MicroStation that can 
install to either Win95, NT or DOS.  I had recently established a config 
file that allowed Half-Life to run on my machine, so I thought this 
program could run with the same config.  Nevertheless, with or without 
the config file the first disk happily copies all its files to its 
destination.  At the point were I expect it to ask for the second CD I 
get the dump below. 
I've Googled around a bit and found only one specific solution for 
Konquerer (http://www.winehq.org/hypermail/wine-users/2004/08/0282.html) 
but it doesn't seem to fit my problem, others have had no reply.
I get a similar dump when trying to install MSOffice, another two disk 
app. 

I have wine-20050419, FC3

Any ideas?
