TRichView.com

I have a program that saves the contents of Richview to an rtf file. If the intended path is a file that is already open, the program crashes. How can I check for this so that I can provide a message to the user to close the file, so that they never get to the point of crashing?

Thanks!

If the file is already used and cannot be opened for saving, SaveRTF just returns False. No crashes must happen.
