for no reason I can see, my project has suddenly stopped rendering any of the telerik controls on a web form in the IDE, Im now getting this error

Error Creating Control - RadComboBoxCategoriesCould not load file or assembly 'Telerik.Web.UI, Version=2009.1.527.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified.


this is the same for EVERY telerik control, it has been fine, but its just come from nowhere.  Ive tried deleting the Telerik.Web.UI.dll filr from my bin directory, that seemed to work initially, but it doesnt make a difference anymore.  Ive checked in my web.config file and I have NO version numbers specified in there.  I have SP1 installed for VS2008.  Can anyone help me with this problem ?

OK, this is getting worse now, not only are the controls not rendering, I no longer have events available for selection.  I also just added a RADTextBox to my page and it crashed Visual studio.  Has anyone else experienced this ?  It seems the Telerk controls are unstable

Telerik Admin suggested that I examine these links

http://www.telerik.com/help/aspnet-ajax/design-time-troubleshooting.html
http://www.telerik.com/help/aspnet-ajax/vsx-telerik-web-design-assembly.html

The third point in the first link helped me to overcome the problem in my scenario

Ive copied the design assembly to my bin directory which seemed to work for a while, then the same problem reappeared.  I think I might have found out whats causing the problem though.  I sometimes have a second instance of visual studio open on my development machine as I tend to take various bits of code out of other projects to include in my current project.  It seems to be that whenever a second instance is open, this problem occurs.  If I shut the second instance down and close and open the first instance, all is well again.  Not really sure why this should be, anyone have an answer ?

I don't have this problem - tried VS2008 and VS2010. Maybe you should try another suggestion.
