Each and every change to fields in the fields properties dialog now takes a long time to be recorded as -- from what I get -- everything is always updated simultaneously (grids, properties pane,etc.).

That might be  fine in a DB without too many fields or grids, but it's extremely slow in a DB with a lot of fields and grids.

 

(I'm primarily working with 77b,but I'm keeping a v78 handy.)
