Veditor "file not found, check filecase"-error

Hi,
since changing from veditor 0.7 and Windows XP to veditor 1.1 and 
Windows 7 I have a problem.
The situation is the following: There are two projects, one with the 
make.exe in it and linked to the other project, which contains the vhd 
source. Now when I have an error which is not found by the veditor 
parser (e.g. writting st_ulogic instead of std_ulogic) the external 
compiler gives an error. The veditor error parser catches this error but 
is unable to map it onto the sourcefile and reports a missing file ( 
"... is not found in the project. MS Windows users, check filename 
case!!!").

I also tried it with veditor 0.7 and I got the same error. Of course I 
compared the filename, everything seems to be fine and as it says 
filename case I tried it with everything written in lower case (apart 
from the drives name).

When everything is in the same project it works fine but it would be 
preferable to have it split in two projects.

Do you have any idea how to solve this issue?

Regards,
Max
