When EnableTrackChanges property of RadEditor is set to true: -The font name of the written text in RadEditor cannot be change and instead the default one is used. This behavior is observed under FireFox, Chrome and Safari. The workaround is to mark the already written text and then set the desired font. -The chosen font size from the toolbar returns to its default value when the cursor changes its position and then returns back to its previous position. This behavior is observed under FireFox.
