Properties are not saved

[Zenute Marins]

We are facing several problems when persisting properties changed at design time. Sometimes with no apparent reason the properties changes are not saved to disk nor showed at run time.
It happens with radtreeview, radmenu, radmaskededit.
Working with imagelist in radtreeview is a nightmare. Changing fonts in radmenu does not work anymore. ExcludePromptsandLiterals works in one machine but not in the other.
Theses problems are driving us insane, since it happens in different projects and different machines.
These machines are running windows 7 and visual studio 2010.
I just can´t believe simple things like these do not work properly. I would like to hear from you what could possibly be happening.

Hello Zenute,

Thank you for contacting Telerik support.

I am sorry to hear that you are experiencing issues using RadControls for WinForms.
Our primary development and test environment is Windows 7 64bit and VS 2010 and we have not observed such behaviors. That is why I want to ask some additional questions:

1. What are your Regional Settings?
2. What is you DPI setting? 
3. How many concurrent installations of our controls do you have?

It is possible that VS behaves wrong if you are using two or more parallel installations on a single machine.
Is it possible to send us a sample project with exact steps to reproduce the wrong behavior - this will help us to locate and address the issues?

Thank you for your time and cooperation.

Kind regards,
Peter
the Telerik team
