New in 1.18.09 (10-7-2008)
Changed position slider to "initial position", becomes disabled after simulation starts
Made default initial position -7m

New in 1.18.08 (10-7-2008)
Removed logo
Fixed control panel layout to get all controls to fit onscreen on startup

New in 1.18.07 (10-7-2008)
Moved position control above advanced control panel

New in 1.18.06 (10-7-2008)
Barriers off as a default
Control the initial position without having time start going by (in the advanced controls)
Starting with the free-body diagram showing as a default

New in 1.18.05 (10-3-2008)
Added trial fix for impulse from wall during collision.

New in 1.18.04 (10-2-2008)
Text boxes accept values when losing focus.

New in 1.18.02 (9-30-2008)
Fixed a bug that set incorrect values for static and kinetic friction.

New in 1.17.21
Fixed: The "Apply a Force...slider" wiggle me can end up in the wrong place.

New in 1.17.19
Control panel no longer resizes on item change: this was done by highlighting the item instead of changing font.

New in 1.17.18
Fixed: The friction buttons do not show the initial state. The state appears to be "on", but the button does not show that it is selected.
Fixed: The text box for mass (in more controls) is not large enough to show more than 3 digits. It should show up to 5 digits (to include 1000.0)

New in 1.17.17
Renamed "kinetic friction" to "coefficient of kinetic friction"
Renamed "static friction" to "coefficient of static friction"
Fixed: The wiggle me help text should be "Drag object to apply a force."
Fixed: Add >> and << to More & Less controls
Fixed: "more controls" button should stay in the same place instead of going to the bottom
Fixed: More controls" should add controls below original "more controls" button (instead of replacing with a separate entire control panel)
Renamed "show component forces" to "show horizontal forces"
Fixed: Stop animating the wiggle me help text after 2 oscillations
Fixed: Remove the selection for different objects when more controls is selected (Should no longer be necessary since the objects will still be shown above the controls)
Changed the friction checkbox into a horizontal layout Friction on/off radio buttons
Fixed: Better layout for gravity & mass sliders, try using linearvaluecontrol, see e.g. optical tweezers fluid controls (applies to all controls in the "more controls" area.)
Fixed: Initial values for advanced controls are incorrect

New in 1.17.15
Fixed: When you first click Graph Force, the slider is very small. It expands when you mouse over it.
Fixed: If you set a force and hit go, when you rewind and playback, the force slider tracks the friction force rather than the applied force.

New in 1.17.14
Fixed: Applied force text box does not update until mouseover. Reproducable by dragging the crate, then let go - applied force does not reset to zero until mouseover.

New in 1.17.13
Removed performance problems with Applied Force text box update and Go Pause Clear button update

New in 1.17.12
Fixed: When you hit the Clear button, the "Apply a Force By dragging the slider" wiggle me pops up.  This shouldn't pop up if there is no slider.
Fixed: the wiggle me is in the wrong position for the slider when it is present (too high).
Fixed: make the checkboxes in the control panel (Show forces, etc.) aligned on the left
Fixed: The Applied Force text box does not update until you mouse over it. This is when entering values,
using the slider, or dragging the object.
Fixed: The Go, Pause, and Clear buttons also seem to stay grayed out until you mouse over them.

New in 1.17.11
Bugfix in strings

New in 1.17.10
Converted FBD to piccolo
Added button to enable FBD
FBD is disabled by default
Fixed: cursor hand should be enabled everywhere on FBD
Fixed: mouse events pass through the "close fbd" buttons and create force
Fixed: the graph label "Force (N)" overlaps the slider.
Fixed: the slider control is only the width of the slider. Makes it almost impossible to see or grab.
When the sim starts, all graphs are minimized and the play area is lower, to be centered in the window of the sim
The outline of the "total force" arrow a dashed line in the play area
Wiggle renamed to "drag to apply a force"
Move "more controls" to advanced panel near the bottom
Fixed: Net force should not appear in FBD
Added check boxes for "Show component forces" and "Show total force"
Moved total force arrow further north to make it appear less like the other forces

9-27-2007: Added slider snap-to for static friction requested to be less than kinetic friction
9-27-2007: Enabled type-in editing during recording
9-27-2007: Updated About dialog
3-7-2007: version 1.01.15
