I'm running an application on a Citrix box and when I hit the page with the CuteEditor on it I get the System.NullReferenceException.Object reference not set to an instance of an object. Error. The application runs perfectly if it's not running on Citrix. I thought this was an isolated error as in it hasn't occured in any other applications here at work, but I found out that on the one other app where CuteEditor is used on a citrix box the same error occurs. Are there any settings I need to change in Internet Explorer on the computers using Citrix to get rid of this error? Any help would be appreciated. Thanks.
