How to prevent dialog after mousing over "Try DraftSight Professional" menu?

I mean, just mousing over it, not even clicking on it?

I understand that DraftSight is a loss leader for SolidWorks and other upmarket Dassault products. I also completely understand the desire to promote the paid versions of the product. I have no problem with that.

But if the menu bar is focused and I move over the "Try DraftSight Professional" menu, it pops open a dialog (that must be manually closed) even without clicking on anything. Is there any way to somehow change that behavior? If I were to choose the 30 day pro trial and then decline (assuming that's possible?), does it then behave like the other menu options?

(DraftSight 2015, 64-bit)

Thanks!
