I'm with @Wallboard and @PUCC_Treas : I just finished all the work I've been trying to do for weeks, all without more than a single hiccup (QB seemed to just quit--no error message. Glitched out when I was importing bank feeds while also entering some receipt details--I chalk it up to a glitch in the matrix). No errors, and I was able to access the Receipt Manager which for weeks has been giving me issues with that unrecoverable error everytime I tried.

MS must have fixed SOMEthing? Intuit certainly hasn't changed anything.
