Hi John,

1) The QUICKSURF error/warning is reproducible, I'll paste the full
console output below. Curiously, by mis-clicking I seem to have triggered
a different error; no STRIDE executable is found:

Info) assignment. Proteins: structure, function and genetics, 23, 566-579.
ERROR) STRIDE binary "C:\Program Files\VMD\stride_WIN64.exe" cannot be run; check permissions.
ERROR) Call to Stride program failed.

(No stride_WIN64.exe in/at this path)

2) GPU is whatever version of a GTX1650 Microsoft used for the Surface Book

Output from \Windows\System32\nvidia-smi.exe (running the new vmd alpha
build)

Note: these are (this is) the driver(s) installed by the Windows
update mechanism, I haven't touched anything nvidia related by hand. I did not
install any CUDA development libraries/tools on this machine.

Copy of output in console window follows.

And, yes, this is amazing progress -- thanks!

PS: All I did was load PDB 1crn directly from the PDB, and trying to activate
QUICKSURF must have by accident hit (New)Cartoon first ..
