well if someone writes that, delete mirror doesnt work since 7 betas and instead of delete does pause or even sometimes crash. then i dont know how to michael i can reproduce better error. because its on every download with mirrors :P
another thing now its its mixed ftp & www downs and you do segmented download, mostly today ftp allows 1 login per ip. but it tries even 4 for 1 ftp, and we got window with login & pass. when you press cancel it also aborts instead of skiping this mirror. and mirrors there are 15 so it can use 10 for 10 segments instead of 3
