Need Help!- X3 hard crash in verify and confused tool paths

[foxsquirrel]

I hope its my fault, since going to X3 it has crashed twice today (same machine that was running X2 for a year). I have a project that has mill and lathe tool paths, different layers for each part. MCamx is getting confused with the backplot sometimes then verify crashes the computer. Verify uses the stock setup for the mill part instead of the lathe part stock setup. Does any one use a single file for a large project with multi parts and tool paths for different machines(on different levels)? Or should this be a single part and toolpath per file?

I have only loaded X3 on one PC for testing so far. But on the others with X2 we have been doing assemblies with multiple parts, some on common layers and some on separate layers, but all use multiple WCS origins. I have some that have as many as 30 parts and more than 600 operations total.
