I have a client who has a website that needs to open up a Rich Text Editor box. When she goes to open up the text editor she gets the error message "Your Web Browser is not Rich Text Enabled". The browser is IE11 and according to everything I have seen, all you have to do is put the website into Compatibility Mode and it will work but it doesn't work on her PC. I tested the website on mine with IE11 and got the same error but as soon as I put the website into Compatibility Mode the Rich Text box showed up exactly as it should. On the clients PC I have tried Firefox and Google Chrome and all of them do not work. I tested Firefox and Google Chrome on mine and they both work. I restored her system back to IE10 but it is still doing the same thing. I ran the reset tool in IE as well to remove all the plugin's and custom settings and still no go. Other users in the office do not have this issue, the Rich Text Editor box opens up just fine. At this point I assume it is some piece of software that only she has installed on her system but I have no idea what it could be. Does anyone have any advice or insights as to what it could be. I spend too much more time on this and I would be better off backing up her data and starting over? I have attached two pictures, one with what the text box should look like and the second is what hers looks like.
