I probably should have put this in the Windows forum; don't know if this works for the Mac.
My problem was that when you right-click on a word (greek, hebrew, or english) and 'search this resource', Logos4 seemed to have absolutely no idea where to put the Search panel among my other panels. When I open other resources, the software seems to try to match up similar tabs. But not Search! It's a free-for-all.
First I tried using the 'Target' ('Send Searches Here'). That worked fine as long as it didn't hit a crash combination (on my PC apparently). Also, I really didn't want it to write over previous searches anyway.
Then I noticed the software seemed to always put Search in a specific place, no matter where previous searches were located. I tried various combinations to see what the principle was.
It turns out (subject to someone else finding otherwise), that the software puts the Search panel in the SECOND PANEL CREATED in sequence in the main window. Not the second panel in the display, but the nth panel created for the main window.
Sooooo .... by carefully building my layout and giving a home for 'Search' in the 2nd panel introduced, all is now quiet and orderly! And no more 'Target' crashes. The Searches line up in tabs really nice and neat for me to review.
