Hi Telerik!
I spent lots of time investigating the following situation.
For some reason the editor that I used to modify Telerik.ReportDesigner.exe.config file switched xml elements names to lowercase.
ReportDesigner was not started at all in that case. Even no error message was shown.
I had to explore system events logs and found that ReportDesigner.exe throwed an System.IO.FileLoadException.
But still with no details.
Only after hours of exploring I found the problem with xml-element names and fixed it.
I think if you add .config file validation with user-friendly messages during ReportDesigner starting it will help.

We have developed additional logic around the Telerik Reporting Engine so I don't know if this would be valuable to anyone else or not but I would love to have the ability to associate custom properties to a control.  

The use case that comes to mind most is the logic we have implemented to auto size text that displays on a report to fit in the area provided.  We use a control naming scheme to determine what controls should be auto sized and how they should be sized in relation to other parts of the report.  It is typically assigned used with a Panel, a TextBox, or an HTMLTextBox.

I would love to have the ability to add two associate two additional properties to these controls that could be used in the stand alone designer to allow users to set an AutoSize (true / false) and a SizingGroup (string) property on these controls rather than worry about making sure the control is named properly.  I would allow users to more easily leverage this functionality.

I realize that it is unlikely that this will be implemented since it wouldn't be widely used but I like to dream.

I want to download patch Q3_2012_SP1_v6_2_13_110 for reporting but unable to get it. I unable to find the link. could you provide link for this?

Running the report book demo in Chrome v "34.0.1847.116 m" under Windows 8 crashes the Silverlight plugin. This does however not happen under I.E 11.
