Using this newest build, and it works perfect on windows XP x64 SP3. Seeding 2 files at pretty much normal speed, mem usage is only 2.5MB, everything's like it should be (although yesterday i had this weird problem, i was seeding the same 2 files I'm now (there were around 300total leechers) and the speed could only reach like 5KB/s . but never mind that, it's all fixed now). Thanks for this release keep up the good work ^^
