Hi All,
Maybe I'm the only one who didn't know this but I thought I'd post this just in case I'm not.
If you are using Project Navigator (PN) and trying to drag a view into a sheet and it takes a long time or crashes on you try unloading the constructs(xrefs) in the view drawing before dragging it into the sheet.
I have quite a few view drawings with many (10+) constructs attached and was having a heck of a time getting them into my sheets. I unloaded the constructs in the view and was able to drag them in without any problems. Then all you have to do is reload the constructs in the sheet drawing.
Hope this helps others so they don't have to go through the same frustrations I did.
