I am having problems with unrar using ark and kde3.5
If I unrar on set of rars in one directory it works perfect, but if I start 2 jobs at once (unrar 1 sets of files in 1 directory and another set in another )then wich ever set finishes unraring first stops both unrar processes ,so I end up with one directory having a perfect unrard file but the other has a currupt unfinished one.
This usually happens when I am unraring avi 350mb + and I usually start 2 or 3 unraring job so I can move away from the pc while they unrar
It seem as though both/all the instances of the unrar program are interacting and the one to complete the job first stops the other.
I think this is a bug but dont know weather it is with unrar kde or linux because I dont know enough about linux.
Because I dont know which is at fault if any I also dont know were to report the bug to
,any help would be appreciated or any advice on how to run unrar through kde without this happening

kernel 2.6.17-gentoo-r4
unrar 3.6 Beta2
kde 3.5
AMD athlon

Thanks for any help
