The problem is old.
This is the link http://toadforsqlserver.com/thread.jspa?threadID=37150&tstart=30 with problem when TOAD 5.8 was still in beta. In TOAD 5.7 the problem doesn't exists.
Now in the official release 188.8.131.521 the problem is still present.
In attach a screenshot of the problem.
Have you intention to solve the problem or not ?
I stay tune for your answer.
