I have the “allow multiple copies” option set.
Leaving 2 Toads running, I eventually get the following in 1 of the processes:
Cannot create file “C:\Users\roeschley\AppData\Roaming\Quest Software\Toad for Oracle\12.0 beta\User Files\CONNECTIONS.INI”. The process cannot access the file because it is being used by another process
The error appeared in the first Toad process I started.
