Browser Tests February 2013:

FGiJ Jmol 13.0.12

Basic operation, checking for problems with
  Jmol flickering
  Hover reports
		Require window focus but not Jmol focus.
  Identity reports
  Centering
  Distances, Angles
  Wheel zooming
	Right clicking on an atom
	Ctrl-Right click and slide/drag
  Right margin zooming

--------------------------------------------------------------------------
OS 10.6.8 Snow Leopard Java 1.6.0_39

COMMON TO ALL 3 BROWSERS IN OS X
		Identity, Centering: don't have to move the mouse after clicking.
			Response is immediate.

		Jmol background flashes black when window is pushed behind or brought
			to foreground, but USUALLY not with view changes. Sometimes tho,
      esp. w/ centering, zoom buttons.
		Right clicking to open menu does not work in the upper left of Jmol.

		Distance FAILS: red monitor line appears on first double click, but on
			single click on a different atom, it disappears. Triple click neither
			starts nor ends. Single click does not start.
  

  Safari 5.1.7
		UNIQUE TO SAFARI
		Wheel zooming works with slow rotation but each notch is a huge jump.


	Firefox 18.0.2
		UNIQUE TO FIREFOX
		Right-clicking opens the menu but rotates the molecule suddenly
			to a different orientation. 
		Wheel zooming does not work when the wheel is rotated slowly, only when
			it is rotated quickly.

	Chrome 24.0.1312.57

		Wheel zoom same as Safari (big jump).
			print mousewheelfactor: 1.15
			set mousewheelfactor 1.02, 1.07, 1.15: wheel stops working.

	Opera 12.14:
		Fails to load control panel in FGiJ 1.46 or 1.47 (local file mode).

--------------------------------------------------------------------------
WINDOWS SEVEN Java 1.7.0_13

ALL BROWSERS:
	Identity, Centering: don't have to move the mouse after clicking.
		Response is immediate.

	Distances don't work.

	Wheel zoom works well!
  set mousewheelfactor works! defaults to 1.15, 1.07 is slower.

	Right clicking brings menu up even upper left of Jmol.

INTERNET EXPLORER 9.0.8112.16421/9.0.12

	When a hover report overlaps Jmol, its image is corrupted
		(double molecule half diameter colors reversed; bottom black).
		Ditto for mouse moving off menu.

FIREFOX 18.0.2
	Hover reports overlapping Jmol don't corrupt it, but mouse moving off Jmol's
		menu does.

CHROME 24.0.1312.57
	Sometimes the entire window goes black when going from window to full screen.

	When a hover report overlaps Jmol, its image is corrupted
		(double molecule half diameter colors reversed; bottom black).
		Ditto for mouse moving off menu.

OPERA seems unable to run local files.
