The following error message is recieved when launching.
"Internal error: Can not load information in <path>\SavedSQL.dat. <path>\SavedSQL.dat has been copied to <path>\SavedSQL.err"
Two Toad's are opened at exactly the same time. Either on purpose or the icon was clicked twice on accident. Both Toads are trying to access the same savedsql.dat file at the same time and one is getting locked out.
RESOLUTION #1:
If you do not need to have two Toad's open at the same time, uncheck the option that allows more than one Toad to be open at the same time. View | Toad Options | Startup | "Allow multiple copies of Toad to be loaded"
RESOLUTION #2:
When both Toads are opened, one will have the saved sql information and the other one's saved sql will be blank. Make sure you close the one with the saved sql information last.
