running two Toads at once

for anyone seeking to run 1 Toad-instance on one monitor and another on a second monitor (like me), WITHOUT the option "Allow multiple copies of Toad to be loaded" checked - because this option gives the pitfall

solution (I have Toad 13.3):
search for "run multiple toad instances" in Toad Help (menu-item Help -> Contents) and choose topic "Run multiple Toad instances" = use startup parameter /VIRTUAL
