Hi Michael,

  I fixed this problem in ChimeraX just now — it was a one line change.  Chimera uses a different window toolkit (Tk) and it would take significant time to figure out the change and test it.  I tried a few simple things that did not work.  All our work is on ChimeraX now I’m not going to fix it in Chimera since I do not have time or funding to work on Chimera.

> Hi.  Here's an issue regarding the use of "Planes" in the Volume Viewer, not really a proper bug but often an inconvenience. When I choose a subset of Planes there is obviously some calculation, and the calculation has to be redone when I move the slider. For a large volume this can be very slow, especially for Surface rendering. If I use the number box to save time, the calculation updates for each change "instantaneously", meaning slowly. For example if I want to move from 110 to 85, the calculation updates for 11, 1, 8, and 85. I think it would be more efficient to wait for an Enter, or even just to add a delay of 2-3 seconds. I hope you can consider this in future versions.
