I've been having a couple problems with the first beta. First off, I can't get rid of a download that completed a while ago whose files I then deleted. Every time I start apexdc, it tries to re-download this file from the hub (it is 6gb) and, since there is no "Cancel Download" button, there's no way to get rid of it ("Close Connection" and "Remove User from Queue" would seem like plausible alternatives, but they dont do anything). Also, the status bar for downloads alternates very rapidly between "Download finished, idle..." and "Download Starting". It the D: counter on the bottom of the screen goes up as if the file is downloading anyway. In addition, apexdc uses 20+% cpu while downloading.
My relevent specs are as follows:
* Intel Q6600 @ 3ghz
* 4gb ram
* 32 bit vista ultimate
Everything worked fine before the update.
