Editor issue in

I’m running Toad and I just had something happen that I
don’t think should have. I had three tabs open in the editor, one SQL and
two PL/SQL, in that order. The two PL/SQL tabs were the result of loading
package bodies in the editor from the Schema Browser, I wanted to make an
additional change to one of the bodies, but being unsure of whether the one in
the editor was 100% current, I closed that tab and then went to the Schema
Browser to choose to load it again.

Even though the tab that had previously held it had been closed, the message
indicating that it was already loaded and asking if I wanted to reload came up.
I said reload and it did load, but overwrote what was in my first tab, the SQL
one mentioned earlier, overwriting its contents.
