Can't pick points to edit in Edit mode in 2.37

Help!

I don’t know if it’s a bug, in which case I’ll report it, but ever since I loaded 2.37, I can’t edit the points of meshes created in 2.36. A new blend file is fine. My old ones open up and everything seems fine, but I can’t turn vertexes from pink to yellow for editing other than the ‘a’ key. Any thoughts?

It seems by toggling the selection mode icon for pick only visible, I retrieved the ability to pick again! However, how come when a vertex is visible, I still can not pick it when this icon is active? Thanks.
