Accidentally triggered a morph search for lemma:ο@DGSM in NA27 - been running for 3 mins now and no way to stop. Had to force quit Logos. This has happened a few times, when I search for something that returns a large number of hits. Each time I have to force-quit Logos, meaning my workspace is not remembered, etc. Not pretty.
Some means of stopping a long-running search should be provided. Simply showing the "spinning pizza of death" isn't appropriate behavior.
The irony is that the search results window showed "4072 results in 1623 verses (0.34 sec)" almost instantaneously, and then proceeded to hang while, I assume, rendering the results. Thus, the search part is probably fine, but the UI part is in need of some serious attention.
