BIRT: Fix for Preview Tab After Updating to IE11

I've come across this issue before, but never had a really good fix until now. It seems that Internet Explorer 11 has all sorts of incompatibilities it introduced, and one of which is with Eclipse. I first encountered it when trying to Preview report designs from withing the Eclipse BIRT Report Designer. It just hangs, it never runs the report. The fix to get preview working again in BIRT is as follows: Change the following Windows Registry Keys HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeaturControl\FEATURE_BROWSER_EMULATION jawaw.exe=9000 change to 9999 eclipse.exe=9000 change to 9999 This fixed the Preview issue. Alternatively, you can change to use an External Browser in Window/Preferences/Report Design/Preview. But this will only work if you go to the Run/View in Web Viewer option.
