Hi,

We have a vb.net project in ASP.NET that we install on many client servers, recently two users have discovered that they can't change tabs on the below page. There's no reason for this to happen, they have the same website files as all other customers, same version of Telerik 2016 Q2 (also tested on 2015 Q3), same IIS installation options. It appears to be a problem with the installation onto the server rather than a browser issue because we can recreate the issue on all browsers. We also have a "cloud" version of the same software which we host ourselves where the same browsers do not present the same issue hinting towards a server issue. The rad tab strip control works elsewhere in the application on the server using virtually the same code and as mentioned before works on other customers servers, so I'm completely at a loss.

 

Any help is greatly appreciated.

 

The page contains a series of textboxes, combo boxes and Checkboxes that I've removed as otherwise it was over a 1000 lines of code!
