Just select a piece of sql statement on a window that has multiple sql
statements and hit F5 to execute the highlighted part. And this error pops up.
Toad does not crash, just hit OK and move on. This error seem to occur at
random. Usuallly I can select and run queries in a window that has multiple
queries displayed, then again sometimes I cannot.
