Hi, i rewrote your script, trying to keep the same variable names but not everywhere.
It does refresh.
You should remove the first entry of your help, a dockable script shouldnt work that way...
(function(theObj){
// "globals"
var uiPal, helpPal, state;
// current state
state = {
dimension : 0,
axisDir : 0,
// userSelection: the last user selection (array of layer objects)
userSelection : [],
// refIndex : the selection index in the dropdown
// if refIndex>= userSelection.length : average
// else the reference layer is userSelection[refIndex]
refIndex : 0,
};
// UI : help palette;
helpPal = new Window ("palette", "KeyFrame Ease : Help", undefined, {resizeable: true});
helpPal.myPanel = helpPal.add("panel");
helpPal.myPanel.myStaticText = helpPal.myPanel.add("statictext", undefined, undefined, {multiline: true});
helpPal.myPanel.myStaticText.preferredSize = [800, 400];
helpPal.myPanel.myStaticText.text = "How to use this script:\n\n1. Before running script make sure that you have a comp open and selected in the timeline. If you do not the script will warn you and you must run the script again.\n\n2. The script populates its dropdown list when first run. If you wish to change the selection of the layers you will be aligning you must press Refresh Selection.\
\n\n3. AXIS - defines the position value you will be aligning your layer items too. That is, will all layers be aligned to the same x, y, or z position.\
\n\n4. AXIS direction defines the which direction the layer will be aligned relative to the reference layer selected in the Align To: drop down. This is analagous to Left/Right justification in print or 2D AE layers.\
\n\n5. Align To: picks which layer will be used as the reference point. ie. If you wish all your selection items to have the same x position as 1_greenSolid then you would set 1_greenSolid as your reference layer.\
\n\n6. Apply runs the alignment.\
\n\n7. If you wish to change the layers that you are aligning then you must push Refresh Selection.\
\n\n8. The Average item in the Align To: dropdown takes all the position values of you selected AXIS and averages them out";
helpPal.layout.layout(true);
// UI : main
uiPal = (theObj instanceof Panel) ? theObj : new Window("palette", "KeyFrame Ease", undefined, {resizeable:true});
uiPal.grp = uiPal.add("group{orientation:'column',\
