Usually, they gzip or bzip2 pretty well.  True it is still a lot to look
at, but if you can isolate a point of interest (the place where it
decides to raise a messagebox, FI - it might take some thousands of
lines of relay trace to actually raise the dam' thing) you can pick a
few thousand lines before or around it to examine or send.
Conventionally, I think we ask for 200 lines before, but we often have
to ask again for another 200.

Sorry, you didn't send it AFAICT.

Maybe.  Why only vfat though?  Still... possible.  The thing wine is
noted for though is that one process can not see the windows of antoher
process, I think, and some windows apps use these for interprocess
communication.  It is on its way to being fixed, but it will be some
time yet.

Did you see the note in <wine>/documentation/samples/config about
directory symbolic links?

; Wine doesn't pass directory symlinks to Windows programs by default.
; Enabling this may crash some programs that do recursive lookups of a whole
; subdir tree in case of a symlink pointing back to itself.
;"ShowDirSymlinks" = "1"

Possible.  Why 2.5gb?  Never mind.  Maybe the sign bit in a 32 bit
integer?

The function that it uses to query file space might not be a file
function.  One thing you could try is a small vfat filesystem:

#!/bin/sh
/sbin/mkdosfs -F 32 -C /usr/local/dose 16384
/bin/mount -o loop,uid=501,gid=14,umask=2 -t vfat /usr/local/dose /mnt/dosed

You will have to change the paths and uid, of course, but that is all
there is to it, then just put it in .wine/config and have a go.  You
need kernel support for the loopback device, but unless you make your
own kernel it should be there.

I only meant that as an example of how sloppy windows apps are with
error messages, particularly message boxes.
