Parts Not Updated With Assembly When SAVED

Using 64 BIT 2009 sp4

I have a 25 part assembly and constantly hit the rebuild button(while in assembly mode, not part mode) and then hit the savebutton constantly (in assembly mode). At some point I finished forthe day and shut the machine off.

Somehow I managed to lose hours of work because the next time Iopened the assembly lots of the parts did not have the latestchanges saved. What the heck happened??

How do I make sure that this never happens again? This has neverhappened to me in the last 5 years of using Solidworks.


Thanks for ANY help.
