cayenne modeler problem on windows

[Tore Halset]

Hello.

Another guy here are using Cayenne 3.0m2 Modeler on windows. When he  
saves the model, once in a while, the changes are not saved to disc.  
Cayenne Modeler thinks the changes are written to disk, but they are  
not.

Anyone else seen this behaviour? We could not see/find any stacktraces?

Regards,
 - Tore.
