Yesterday, and today, I have seen a very strange occurence. During working in a big sub-assembly, which is part of a bigger assembly (opened as well), I saw that a lot of parts and sub-assemblies suddenly were unsuppressed! I am wondering why this happened, because this was not what I wanted to happen. I can't find anything about this on this forum. But somewhere else on the web, I've found that it has something to do with unsuppressing something by using the "edit - undo" button. But I cannot confirm this. Somebody an idea?
Would be nice to find the reason for this, so I can avoid to do this action.
I am using Solidworks 2010 SP4.0 x64.
