After a lot of fumbling around to figure out why the popup text on image maps in SharePoint 2010 weren't working, I figured out that IE8 and Chrome don't use the ALT tag any longer in image maps. . .they now use the TITLE tag to show tooltips or popups on image mapped items. However, the version 6.3 of RadEditor for SharePoint 2010 that I'm using doesn't support the TITLE tag - only ALT. Is there a plan to change this in a future version, or is there another workaround other than going into the HTML source and changing it?
