wine users - Apr 2005 - Help with debugging fatal exception in Dreamweaver

Hello list.

I've been bantering back and forth with some members here regarding a fatal
exception I get when starting up Dreamweaver. I am running Mandrake 9.1
(Kernel 2.4.22) and wine 20050419. Dreamweaver was installed with wine
20040408 and I have tried other versions in between.

The error is "Dreamweaver encountered a fatal exception. Dreamweaver will
now terminate."

Anyway, I've been doing some mad debugging, and dissecting of log files.
Here's what I've got so far. I would really appreciate some input.

~~* From the log file (WINEDEBUG=+all wine Dreamweaver.exe > log.txt) *~~
(NOTE: initial numbers are the line numbers of the log file, so they can be
ignored.)

____________________________________
obviously, my problem has something to do with ws2_32.dll, which I've
replaced to no avail. I see that WS.gethostbyname returns nothing and fails.
What can I try to get around this problem? is my hostname invalid or
something?

Thanks in advance.

Yeah, a NULL return means an error occurred. Most likely it's an invalid
address, I get an NXDOMAIN for "IBMFB1L0DH.ercsarnia.ca".

Clearly Dreamweaver isn't expecting that call to fail as it doesn't
bother
checking the return result (assuming it's Dreamweaver that makes the call
and not Wine itself). So the questions are:

1) Where does this name come from?
2) Why does it fail?
3) Why does Dreamweaver not expect that?

You need to do some more research I think. Try grepping the logs for that
name and see where it appears first.

BTW a +all trace is usually overkill, +relay is enough
