That sounds to me like an issue with your computer processing speeds. I would recommend finding an IT person to come in person or to remote in to run some diagnostics.

FWIW, I run Lacerte hosted on RightWorks. Updates get auto-installed around 11p/midnight PST. I only get closed out of the program for max five minutes, usually less than 1 minute.  Some people don't like it, but it's worked great for my firm, so it's been worth the money.
