strange groaning noise
This happened twice yesterday (never happened before this) -- once while in Firefox and once while closing out of FF and trying to shut down. Both times there was also strange behavior -- first time a form I opened in FF kept hiccuping and duplicated itself many times; second time I couldn't use pulldown menu for several seconds. Any ideas? I'd rather hear it's a software (FF?) issue and not a hardware issue.😕
