I am working on a assembly with several sub assemblies.Yesterday, my main assembly was fine with no errors. Within themain assembly, one of the sub assemblies has 4 differentconfigurations, all which were fine.

I just opened the main assembly only to find mate errors in subassemblies which not have been worked on or modified in any way.
Then when I started to repair the mate errors, which I could see noreason for, SW just shut itself down completly, no warning, noerrors, no nothing. Some days it's 2 steps ahead and 4 back??????

What ever happen to SW stability?
