Here is a guess.  Some versions of Xlib will look at a display name
such as "Balki:0.0" and use Unix-domain sockets if it specifies the
local host -- other versions of Xlib will always use Internet sockets
with this type of name.

So ... If MOLDFLOW is built on the latter type of Xlib (always use
Internet sockets if a hostname is specified), then when you changed
DISPLAY from Balki:0.0 to unix:0.0 you switched from Internet 
sockets to Unix-domain sockets.  Perhaps your update to 7.05 broke
Internet sockets somehow?
