I've noticed that the search dialog gets placed under the mouse, wherever it happens to be. However, I have a toolbar with a strut at the top of my screen, and Nedit will place the search dialog under it if my mouse is there. `xprop -root' shows that the toolbar height is included in the _NET_WORKAREA property.

I'm afraid we have to let this stand. NEdit has too many issues in environments it is supposed to work in than to take on new environments.
(This should be moved to feature request later if no objection comes up, so I let this open.)
