Slow typing speed when Trackchenges or Comments enabled

[Ardian]

Hi there,

When I enable TrackChanges or Comments in markp, the speed of typing decreases dramatically. When trackchanges is set to true then the typing speed is normal, when it's set to false typing speed decreases. Why is this happening, i just cant seem to solve this. I'm using this version of AJAX Web UI 2012.3.1308.35.

P.S. When there is no comments or TrackChenges enabled the typing speed is normal.

Internet Explorer 9 is affected only both in compatibility and non compatibility mode.

This is html Code

Hello,

We are aware of such an issue related to slow performance when "Track Changes" and "Comments" functionality is enabled. The good news is that the problem is already fixed so I recommend you to upgrade to latest version of RadControls which is currently 2013.1 417. You could also try this behavior on our online demos:

http://demos.telerik.com/aspnet-ajax/editor/examples/trackchanges/defaultcs.aspx
http://demos.telerik.com/aspnet-ajax/editor/examples/comments/defaultcs.aspx

All the best,
Misho

Thanks I will give it a try.
