On Windows 7 with Internet Explorer 10 i got a blank screen on opening a report or report studio.
Apply the following to solve this:
1. In IE select TOOLS > OPTIONS > SECURITY
2. Select CUSTOM LEVEL and look for ‘Enable XSS filter’
3.Set the value to ‘DISABLE’ and choose YES on the warning
4.Click OK and restart IE
If above doesn’t work try to switch the ‘COMPATIBILITY VIEW’
