There no .dwl lock file when open the drawing

[bingwen3952]

 - Problem: 5 users of AutoCAD Electrical open the same file. There is no warning or interlock of any kind. The last user will overwrite other's working once saving the file. As I noticed, there is NO .dwl lock file generated by CAD when opening the drawing from CAD or project manager.

 - Environment: Windows XP on Parallel Desktop 6 for Mac, AutoCAD Electrical 2012, the drawing files are saved on MAC server.

 - The same problem won't happen on AutoCAD LT or AutoCAD for Mac.

Any ideas or inputs are appreciated.

We are getting the same thing. Not sure why there's no DWL file being created (sometimes)?  We are using Windows 7 on a new computer

Where are the files located?
How are you connected to that location?
