Did you click on the left/right window sizing tool? Look to the far left of the Toad window and click on the small vertical bar about halfway down the left side.
I'm actually not talking about the Schema browser, but the menu toolbar that says "Current Schema". It's a little drop-down list menu bar that allows you to select the schema you'd want your SQL to run against.
