I've noticed that IE consumes huge amounts of memory after I've had Roundcube running for a while. My use model is to fire up Roundcube when I get to work, leave it running all day, then logout. Come back the next day, fire up Roundcube (in the same browser instance), etc repeat for days/weeks until I reboot the system.
When I finally do exit the instance of the browser, it frees up 300+mb of memory (according to TaskManager).
Is this simply the browser keeping too much history, or is Roundcube not cleaning up after itself? Anyone else had issues like this?
