This is a pretty small issue but bothered me enough to report it.
Recently the number of schemas I have to managed has about tripled with most
having the same names across several instances.
Seemed like a good idea to start creating a color scheme in the session
However, when I open a recovered document from a TOAD crash for which the parent
schema is not currently open, TOAD helpfully opens the schema but in the process
removes the color coding.
