The one I'm refering to is "Hildon Bug" that clogs the destop, making it slow, unresponsive. From what I understand you have to reboot the device for it to correct itself but it just repeats itself upon daily usage. From what I know this sluggish behavior happans after a few days or so. I'm not sure were it is on "Bugzilla" but I see it pop up a lot in the threads. I also think their not sure what causes it. I was just curious to know if it's been addressed in the update or not but it maybe to soon to ask.
