Hello, I have installed the compat-libstdc++-33 rpm but I still the same have the problem. I don't understand what this means in the FAQ: anonymous wrote : In case you have the library installed and you still have issue with starting the visual page editor then close all browser views/editors and leave one visual page editor open and restart eclipse. This should force a load of the right XULRunner viewer. Exactly what do I do? The sentence is very confusing. How do I leave one visual page editor open while closing all browser views/editors and restarting eclipse?
