Quanta getting quirky

Over the past couple months I've been hitting Quanta pretty hard. After 
a week or so and a few hundred web pages gone through and seven or eight 
still open it starts to get "quirky". Things like shortcut keys not 
working properly, tool bars disappearing, strange behavior in general. 
Usually shutting it down and reopening fixes it.

Am I just hammering it to hard or is there some problem that should be 
reported.
