Hi Jon,

My plugin uses a generic dialog, but it pops up in an inconvenient place.

From what I can tell, GenericDialog.showDialog() calls GUI.center(this) and
then blocks, which doesn't leave much wiggle room for moving the dialog
around. Maybe Wayne will have a slicker solution, but one thing you can do
is react to a windowOpened event to immediately move the dialog as soon as
it pops up. The downside is that the dialog will momentarily flash in the
wrong place. See the plugin below for an example.

HTH,
