I have the latest 14.4 Lubuntu (Spanish) version already updated. I have found the same bug in two machines. The machines are a 11 year old P4 2.5Ghz, Geforce mx 420 and a 9 year old Dell laptop Pentium Cetrino 1.7 Ghz.
I can focus the cursor on any dialog appearing in Chromium: URL bar, gmail dialogs, composing messages in gmail etc, but I am not able to type anything on them. When I type nothing happens. Is this a known bug in the latest Chromium version? Anything else is correct. I can browse normally and websites are rendered correctly.
I have tried to resinstall Chromium in the two machines and I have deleted the Chromium profile dir but I still unable to type anything, even with a new profile. Firefox runs flawlessly and any other things in the PCs are Ok.
