I'm getting a 500 error, "A potentially dangerous Request.Form value was detected from the clicent," in the Desktop > Introduction > Overview example.
I may not have the sequence of this exactly right. I think I
1. "Logged in"
2. opened the Accordion Window and closed that.
3. Opened the Notepad and closed that.
4. Opened the System Status. I did not close this.
5. Then clicked the Start button and settings. A window opened with a 500 error.
A window popped up.
Status Code: 500
Status Text: Internal Server Error
Server Error in '/' Application.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ctl10="Some <b>rich</b> <font co...").
