How to repeat:
If, upon startup, one clicks on a table name from the Schemata list and
drags it into the query area, the application crashes (rather than showing
"drop action" pop-up as expected).

This bug occurs when view is "Expanded Query Area" upon startup.  It
does not occur if the view is "Normal View", or if the view is changed
from "Normal View" to "Expanded Query Area" after startup, though in
this case the "drop action" pop-up is in the middle of the query area,
rather than at the bottom, as expected.

NOTE: The program *must* be started with "Expanded Query Area" open per default for this error to occur.

Suggested fix:
