As follows...
-----------------
1579ThreeTweaks-di -- Dan Ingalls -- 27 October 1999
Fixes a bug in FileList shiftedYellowButtonMenu and cleans up a few obsolete methods.
Changes the tests in ParagraphEditor dispatchOnCharacter so as to avoid ctrl-key combinations being masked by some non-shifted command keys (like pageDown).
Externally (re)sets the preference Preferences fastDragWindowForMorphic to true.

1580windowColorTweaks-sw -- Scott Wallace -- 27 October 1999
Fixes up the default window colors for a few neglected items -- assembly areas, scripting areas, and selector browsers.
In the face of current poor support for translucent colors in system windows, no longer admits translucent colors as window colors.  This is a temporary workaround!
Also circumvents some very unfortunate window-color consequences when a black or near-black color is reported from the color picker upon mouse-down in the translucent box and mouse-drag across a picker border line."

1581checkForUnsent-sw -- Scott Wallace -- 27 October 1999
Adds a feature in the change sorter allowing you to check a change set for unsent messages.  Look in the shifted side of the change-set-list's menu.
Also fixes the long-standing bug that included, in a method-list browser for a change-set, vacuous entries for methods added but then removed.
Also fixes a bug in update 1569 that could make MethodMorphs work improperly for class-side methods."

1582threeMore-sw -- Scott Wallace -- 27 October 1999
(1)  Fixes a bug that created a spurious extra player when you open a flap-based viewer on a flexed morph that previously was playerless.  (A symptom of this was that the thumbnail of such a viewer did not reflect rotations of the object.)
(2) Makes the second default category for an unscripted player be color-and-border rather than the boolean tests; this is primarily because the isOverColor  computation in the 'tests' category is so slow, allowing the casual presence of a viewer or two on the screen significantly to degrade performance.  Now you'll not get the tests category inadvertently.  Correspondingly, the 'colorUnder' slot,is no longer shown in 'basic' category, because it will already be seen in the color-and-border category.
(3)  Fixes the ever-since-flexing-came-along bug that sometimes made a clone obtained via the duplicating handle be wrongly positioned when the clonee had been a transformed object inside a window.  The clone now appears under the cursor as intended."

1583graphicalDict-sw -- Scott Wallace -- 27 October 1999
Some improvements to 'graphical dictionaries', such as the one you get when you inspect the ScriptingSystem's form library by evaluating
	'ScriptingSystem inspectFormDictionary'
(1)  You can now directly repaint any object you see in the dictionary -- via the new 'repaint' command in the menu.
(2)  A 'find' command is also added to the menu, allowing you to locate any object by name.  The search starts after the current entry, and wraps around to the beginning if necesary, and is case-blind, and is done keyword-fashion, so that any picture name containing the search string anywhere within it will be found.
(3)  A menu icon is supplied rather than the former textual <> button label.
(4)  Balloon help is provided for all the controls."

1584MoreFlexTweaks-di -- Dan Ingalls -- 27 October 1999
Reduces the step rate of ThumbnailMorphs from 20/sec to 4/sec.
Allows SystemWindows to be flexed, and they collapse flexed as well.
Causes scaling of flexMorphs to stick around multiples of 0.25 if shrinking and 0.5 if growing.
Tweaks transformationMorphs to yield faithful 90-degree rotations.

1585chgSetWakeup-sw -- Scott Wallace -- 28 October 1999
Fixes the bug that made single (simple) change sorters not wake up properly."

1586FlexTweaks2-di -- Dan Ingalls -- 28 October 1999
Two fixes for flexing of SystemWindows:
Causes both collapse point and fullFrame point to be properly tracked.
Defeats fast drag and fast reframe when flexed, as these dont' work right then.

1587SWwindowsIn -- Dan Ingalls -- 28 October 1999
Causes collapseAll and expandAll windows to include flexed windows.
