We have noticed that opening Library Specification Groups, Projects, Edit Design Data, etc. is MUCH slower, now that we've implemented formulated materials (of which we have A LOT).  Do other users experience the same issue? 

We are still re-building our library, so we don't have any real data to test, but I was curious at what points does MV go through the "Updating All Formula Driven Materials in Workbook" steps?  I expect we will see these delays anytime it goes through that process, which I'm afraid is going to be very frequent...
