I am having an issue with html screen. If I have a textbox I want to add html to, the screen freezes - the only way to stop it is to hit Alt-F4 & get out. Also, if I have a link, file, etc & click the html button - the same thing happens. The screen freezes & I must hit Alt-F4 to get out. It's like the html box opens but I'm not seeing it.

I am running Windows 7-64 bit. I haven't had any issues up to now.
