I’m still getting frequent Toad Crashes on build 220.127.116.114 when writing sub-queries.
In this screen capture you can see that I had started keying a sub-query above some existing queries. Doing this always seems to make Toad Crash.
The work around seems to be to try to remember to always write both brackets of the sub-query first:
and then position the cursor between those brackets before actually keying the SQL. But really, Toad shouldn’t just be crashing like this.
