1. We developed UserControl in ASP.Net and placed CuteEditor control On it. Let we call as NewCuteEditor. This NewCuteEditor Placed on the WebForm and executed the application it worked fine with version 4.5(Trial). Then we purchased CuteEditor For .Net version 5.0 and repeated same thing then received error as "Exception of type System.StackOverflowException was thrown." After receiving error we revert back to the CuteEditor version 4.5 and received same error for 4.5 also.

Exception Details: System.StackOverflowException: Exception of type System.StackOverflowException was thrown.

2. We also used CuteEditor for .Net version 5.0 control on WebForm and execute it and we found that Font Type and Size feature are not working.

3. We placed more than one control on the same WebForm.
 If we change the any feature of one control(CuteEditor) and switch to another control(CuteEditor) then it automatic reflect the same feature to another control(CuteEditor) also in version 5.0.
