this.setColumnSizes will throw error in ie8

hi.
in ie8. sometime will error in below code in dhtmlxgrid.js :

this.init=function(e){

_isIE && window.setTimeout(function(){
c.setSizes && c.setSizes()
}

setSizes -> setColumnSizes

this.setColumnSizes=function(e){

this.obj.style.width=a+“px”;
this.hdr.style.width=a+“px”;
if(this.ftr)this.ftr.style.width=a+“px”;
this.chngCellWidth();
return a
};

in above setColumnSizes function. the a will be -3 or something that less than 0. so will throw erro.

Thanks!
