Editor is too slow to use

[Tim]

Has anyone experienced this issue with the HTML Editor?  Often times I am unable to simply type into the editor. I may have to wait as long as a minute to see the 2 or 3 characters I just attempted to type. It makes the editor unusable.  It looks like I am using version 2013.3.1140.40

Hello Tim,

This might be a result of some custom code handled via the OnClientLoad event. The RadEditor itself on a simple page opens directly and loads the content area immediately.

If there is any specific configuration used, with which to reproduce the issue, you can provide some markup or code examples, so that I could test on my end with it.

More times than not the issue is when we are enabling 'track changes.' I have seen from older posts that this has been an issue. We are not doing anything special with the editor and using one of the default tool sets provided. We do not have any issue loading the RadEditor, it comes up as expected.  To reproduce you would simply have to enable track changes and attempt to edit some existing text.  It will take 30 seconds or longer to simply highlight  text and more times than not IE10 throws an error saying 'long running script' and that's the end of it.

The editor is basically unusable in this state.

There is no OnClientLoad going on. Here is how we init the control in our ASPX page

                    <telerik:RadEditor ID="RadEditor1" SkinID="DefaultSetOfTools" EnableTrackChanges="true"
                        runat="server" Width="790" Height="400px" ToolsFile="~/xml/FullSetOfTools.xml"
                        ImageManager-ViewPaths="~/Img" ImageManager-UploadPaths="~/Img" ImageManager-DeletePaths="~/Img"
                        EditModes="Design,HTML,Preview" ImageManager-MaxUploadFileSize="2097152" OnClientPasteHtml="OnClientPasteHtml">
                        <TrackChangesSettings CanAcceptTrackChanges="true" UserCssId="reU0"></TrackChangesSettings>
                        <Languages>
                            <telerik:SpellCheckerLanguage Code="en-US" Title="English" />
                        </Languages>
                        <Content>                        </Content>
                    </telerik:RadEditor>

Not a lot going on.

Hi Tim,

The usage of the Track Changes feature is quite relevant information when it comes to RadEditor. With the used version, there might be issues. Recently, improving the Track Changes functionality was an ongoing task and many improvements has been done.

Due to that, I suggest considering to upgrade the used version to a more recent one (best-case scenario - using the latest one - 2014 Q3). You can test the same feature in a real-live example in this online demo.
