I've been using a RichTextbox (RichTX32.ocx) in a VBA Form for the past serveral months. All of a sudden, I started receiving error messages. I checked the form and noticed that the RichTextbox somehow got deleted. When I try to put it back on the form, I receive a message that says "The subject is not trusted for the specified action." What happened? Can this be fixed? For now I'm using a regular txtbox but I could do a lot more with the RichTextbox. Any ideas would be appreciated.
