This is getting ridiculous. First various problems with ED2K support and now this.
I click a search results tab, click some stuff, click Download. Click another tab, click some files, click Download. Click a third, click some files, click Download -- bang! 100% cpu use and UI totally unresponsive. It's still that way after more than five f*cking minutes.
Fix the bloody bugs, especially the showstoppers that hang the entire program, and get 2.5.4.0 out the door already. You've as much as said one of the more serious ED2K bugs is fixed in your development repository, and the random hangs have gotten numerous complaints from numerous users for months now, so you've had plenty of time to fix those too.
Nothing is stopping you making the fixes available to the general user-base except, as near as I can tell, laziness.
Get cracking!
