This thing is really a piece of poo. If I have a long running query and try to do *anything* else within TOAD, it hangs and crashes. Also, the SQL parser leaves a lot to be desired and some DDL statements I've written just seem to silently fail for no apparent reason, yet they work fine in sqlplus. It also screws up placeholders sometimes.
Oh, sure, I could select the option to thread the queries to try to avoid some of the problems, but I'm too paranoid about the "runaway query" and a call from an angry DBA. Besides, I shouldn't have to do that.
However, I like the schema browser way too much to give it up, and that's pretty much all I'm using it for at the moment. I shoulda stuck with 6.x.
