If the problem still occurs, open a support ticket and send us a demo project reproducing the problem on your machine and details about the tested environment. The information will be used to perform local tests.
In parallel, test if running the local demos installed under C:\Program Files (x86)\Telerik\Reporting Q1 2015\Examples
in your test environment results in the same problem.
