It’s possible at some point recently, the secondary window was placed on the TV (second monitor) And every time I attempted a Search/Replace the Search Dialog was being sent to the second monitor (even when the TV wasn’t on?) and even though the secondary EmEditor Window was on the current desktop…
Perhaps a sanity-check could be added to the Various EmEditor pop-up dialogs to force them onto the primary desktop – if the Editor-window in question is on the current primary desktop.
Sorry for the run-around, it was only after re-activating Stardock’s WindowFX-5 that I could see the “animation” of the Search dialog appear, do a little dance and then disappear. Prior to re-enabling WindowFX-5 – the search dialog, if it appeared at all before disappearing off the screen, was so brief as to be almost undetectable.
