PrintPreview is broken in 8.3 (SmartClient_v83p_2013-08-08)

[genev]

PrintPreview functionality is broken in 8.3.
It seems to be working for Timelines/Calendars but not for anything else.

SmartClient version: 8.3 Pro - SmartClient_v83p_2013-08-08
Skin: TreeFrog
Browsers: Chrome, IE8, FF

js error in ISC_Grids.js
_9 is undefined
[Break On This Error] _5[_5.length]="</TR>"}}else{var _5=["<...uttonTitle(_9.masterIndex),"</TD>"])}


Last known build it was working with: 8.3 Pro SmartClient_v83p_2013-07-07_Pro

The following code used to work in all previous versions and builds of SmartClient Pro on all browsers. After upgrading to SmartClient_v83p_2013-08-08, it gives the above JS error on FF, Chrome, and IE.

isc.Canvas.showPrintPreview(hpane,{},{dismissOnEscape:true,width:'69%',height:'90%',autoCenter:true})

//hpane
isc.HLayout.create({
	ID:"hpane",width:"100%",height:"94%",top:43,
	members:[
		isc.SectionStack.create({
ID:"sectionStack",visibilityMode:"multiple",width:"33%",height:"100%",showResizeBar:true,border:"1px solid blue",
			sections:[
.....

getPrintHTML() is working fine on all components but showPrintPreview is broken.

thanks,
