I have been using Bible works since vs 1. Currently I am running a MacBook Pro. And although I have the "64 bit' version running in Mojave, I am considering going up to Catalina or Big Sur. So I have tried to install BW in Crossover several times and it sets up easily and runs but is glitchy. The biggest glitch which seems to cause the others is when I go to the vs1 tab and switch resources like from the NA28 Apparatus to Nicoll or between any of them, it will not switch and although the BW itself continues to run (with vs1 wind blank then) it becomes gradually more and more unstable. If I restart BW, it will open with whatever resource I had previously tried to switch to before the hang, but again if you try to switch again the same thing will occur. Any idea what is causing this? Super thanks for any help!
