Hi
Just installed 1.5.0.15 ( on 3rd sept) and the first thing I did was to got to the help page.
As soon as I tapped a letter on the KB, the whole thing fell to earth.
I enclose a copy of the exception notice (which only remained visible for about 1 sec).
I tried uninstalling, running CCleaner and re-installing to no effect.
Has anyone else had any probs?
