Hello all, I am on an Apple M1 and have just updated to ChimeraX 1.7rc202311210000. I am just starting to learn how to use ChimeraX from the command line (Terminal). My code that ran from Terminal on ChimeraX 1.6 doesn't seem to be working now with 1.7. Specifically, it seems that the dockprep command now ends by automatically popping up a dialog box prompting you to save a Mol2 file. I think this is causing problems when I try to run in nogui mode. I will include the "error message" at the end of this message, in case it is helpful. If this dialog box is the problem, is there a way to suppress it? Thank you!
