A user added a content editor web part with just some simple HTML formatted text to it today. Once the text is added and the page is saved no body can seem to edit the web part's properties unless they use designer or Chrome/FireFox. I find that a bit ironic... But anyway, I have tried IE compatibility settings back to IE7 with no change in the behavior. This has worked in the past, I was mostly wondering if anyone has experienced this recently and if so, were you able to correct it? We have tried this with four different systems, all running IE9 one is not domain joined and the site is in the trusted sites list.
Unfortunately I was only concerned with getting it to work and I copied the HTML into NotePad++ and removed all of the additional blank DIV tags and even some XSLT that should not have been there. Once I did all that it worked. I should have taken the time to actually find out what was causing the problem. Sorry I was not a little more diligent. I suspect it was the XSLT.
