Quote - I use the same library in P8 and PP2010. I don't seem to have the problems the OP appears to have. Mind you, I do have a fair few runtimes.

I remember from P7, whenever I changed to a larger runtime, there used to be a looooong lag time. Does anyone else remember those?

P7's library loads quickly for me. P8 takes forever.  It also takes a while for it to refresh. A problem I don't have with P7. The biggest drawback with P7's library for me was the cascading menus. It took forever to load them.

Of course, one of my runtimes is pretty huge. Maybe I should divide it up.
