I have a long standing annoyance that has been around since the redesign of the datapump utility back in version 10 or 11.
Say I start a long running query in a editor window A, say it runs for 5 minutes.
Meanwhile I wish to export some stuff with the datapump export utility.
So I run the datapump utility object search to pull up a list of stuff to export. At this point TOAD locks up and stalls until the query in editor A completes. There is nothing to do but wait it out or force close TOAD. Seems like there is some kind of simple conflict happening between the two tasks.
