When I try and access a .dwg file located on a network drive I get the following error:

DraftSight Alert

Program must close. Before the program close, you can try to save changes in:

C:\\Program Files (x86)\\Dassault

Systems\\DraftSight\\bin\\NONAME_0_recover-0-2011-04-11.dwg.

Any changes that are save are those prior to the last command you used.

Do you want to try any save changes?

It will only do it for certain directories.  Example S:\\643.  I don't have any problem on our xp 32bit computer.

Has anyone else heard of this?

Thanks
