Hi Ken,

 

I just found out that there is some problem using in JS (prototype) this line:

$get(this._Uploader).internalobject.insertBtn.style.display = "none";

 

Somehow the internalobject or insertBtn is null or empty so there seems to be two dots ".." generated on js code.

 

Replacing that line with this one solved the problem:

 

$get(this._SelectFilesButton).style.display = "none"; 

 

I'm using external button for this to work. but so far seems ok. Thanks for your help.
