[Jmol-users] Bugs in 11.2.0-11.3.0: hover, zoomto (center)

[Eric M. <em...@mi...>]

Dear Bob,

I have been testing Jmol applet prerelease 11.3.0 downloaded from 
sourceforge today. I think I found two bugs.
BOTH OF THESE BUGS ARE ALSO PRESENT IN 11.2.1.
The ZOOMTO BUG IS PRESENT IN 11.2.0.
The ZOOMTO BUG IS PRESENT IN 11.1.49.
I think the hover bug is also present in 11.2.0 and 11.1.49 but it is 
tricky to be sure.
BOTH bugs are ABSENT in 11.1.12.

1. Often there is no hover report. When there is none, I cannot turn 
it on with "hover" or "hover hello". Sometimes I get hover reports at 
the outset, but then none. I have not been able to discern what 
inactivates hover. However, the same scripts leave hover intact in 
11.1.12. So something about hover has changed in 11.3.0 that makes it 
seemingly easy to disable.

2. "zoomto" with no parameters fails to zoom 2X as it did in earlier 
versions. Similarly, "zoomto out" does not change the zoom in 11.3.0.

3. zoomto (center) results in an incorrect center when a range of 
residue numbers is the atom expression.

Parenthetically, in Jmol 11.1.12, with "set debugscript on", the 
report for "center 59-75" is

script 5 started
center  59-7519200
Script completed

Notice the apparently spurious "19200" appended. However, the command worked.

In Jmol 11.3.0, these commands center correctly (but fail to zoom):

zoomto (59)
zoomto (75)

This command works correctly but is reported without the dash with 
set debugscript on:

center 59-75

script 22 started
center  59 75
Script completed

This command centers the molecule incorrectly (WAY off the intended center)

zoomto (59-75)

script 23 started
zoomTo ( ( 59 -75 ) )
Script completed

-Eric
