I did a search and found some threads about dopus taking a long time to load sometimes or after it loads it spikes the cpu. My dopus (220.127.116.11) seems to work great but once a day, usually near the tail end of the day, it spikes my main processor (I'm on a dual proc) and it just stays there. I've tried waiting, I close any open dopus windows and the process remains open and spiking. I have to forcibly close the thread in my process list and then I do a windows-E to bring dopus back up and it's fine. I don't get what's up but thought I'd report it, it sounds like some sort of process is getting hung up or something.
It always happens when it's in the background and I'm not messing with anything. It's possible it's related to ftp as I have an ftp tab open most of the day (I do a lot of downloading and uploading). Perhaps it's possible it's trying to keep the link alive and can't because the server has quit it or something ... not sure what's going on. Other than that a few tabs open on my hard drive is the only other thing going on.
