[bug report] Update Checker Memory Leak

[kiehlster]

Hey, the Dxtory update notification (Update Checker) program has a rather large memory leak in it.  I don't know how long it was running, but just this evening when I discovered it, the program was using up 687,000kb of memory.  By the time I was able to get to the forums and start reporting this, that climbed to 700,000kb before I finally terminated it.  I've attached a screenshot of the task manager showing it using up a huge chunk of memory.  For the record, I'm currently on v2.0.120, though I will be updating now that I notice it's overdue.
