HI Coolio,
What version of IE are you using? Did you try the same method that I followed
Open IE > press F12 and change Browse Mode to IE 10
However, I assume this issue is resolved in 4.1 SP2 Patch 1. See following release notes
"ADAPT01712164 Description: BI Launch Pad fails to render BEx application with Internet Explorer 9 or higher version.
The root cause is that BEx inherits HTML5 DOCTYPE from BI Launch Pad. As a result,
Internet Explorer 9 (or higher version) launches BEx application in Standard mode which
is not supported by BEx.
New Behaviour: BI Launch Pad now launches BEx application in a separate window and renders BEx in
Quirks mode."
