Hi @paul.hill
Sorry 14.0 caused lock ups. I believe those are fixed in the current beta, and they seem to be fixed for @raul.kaubi too.
I hear you about quality. My goal has been to get Toad as solid as possible. I know users are tired of problems, and I want to fix them. We do perform a lot of testing, but it's impossible to predict everything that could cause a problem. I can tell you that I've been primarily focused on bug fixes for the past few versions.
Please try the beta. Toad for Oracle 14.1 Beta. You have to keep 14.0 installed to run the beta, but you can also keep 13.3 installed too. They each keep their own copy of settings, and run completely independent of each other.
