I've used Ajax HtmlEditor control in asp.net web application; it works perfectly on developer PC, i can save record, edit and view record.
Now i've created a complete new setup in other PC; i've installed IIS as well as .net framework. Web application works perfectly on that new PC except that Ajax HtmlEditor control. Black space displays at that control position.

Please suggest me some way so that i can solve this problem.
Thanks in advance.
