When I scroll down a page displayed as rich text in the radeditor using the mouse wheel, or by sliding the editor's scrollbar towards the bottom of the page, phantom line droppings appear over the text that scrolls up from the bottom of the editor's frame. More precisely, numerous light grey 1pt thick horizontal lines are drawn across the text set at random intervals ranging from a few points to a couple of text lines apart. As soon as I move the windows mouse pointer to outside of the radeditor's control boundaries, the lines disappear. I've seen this behavior in other sites that use the telerik radeditor such as the forums in http://devhub.author-it.com/
As a user trying to key text into the control, I find this behavior most annoying because it obliterates the readability of almost everything being displayed, rendering the point of having such an editor available in the first place as being useless. I have to spend time haphazardly scrolling the text up and down until I can get a clean display in which I can find the location of what I want to edit OR review.
As a developer, I'ld like to find a way to prevent these lines from ever appearing. What's causing this problem and how can it be fixed? It doesn't seem to happen when the editor is working with plain text.
I'm using Telerik RAD controls 2011.2.915.35 in visual studio C# build 91605-270-2201135-60151 and am viewing this on Internet Explorer 9 (9.0.8112.16421 with update version 9.0.3) on windows 7 SP1
