there are two video files i have downloaded over the last three days which i cannot change, move or delete, as when i try, i get "file in use/the action can't be completed because the file is open in another program.  close the program and try again".  i cannot close the program, as it is not open.   it is not in use anywhere, by anyone [at least, that i can see...].  it is not being uploaded, nor does task manager show any program open other than winmx.  the file is not virus-infected [as far as my ca security suite can find], there is no malware detected, and so on.  i've got my fingers crossed that this is not a big, weird problem [or if it is, that someone can assist in rectifying the situ], as one of the files keeps crashing divx--which is making me feel there's something wrong with the file.  BUT, the other file i can't move/change/delete was an exact duplicate of one i already have [which works fine], so i don't know... i've uninstalled and reinstalled divx, which helped nothing.  another odd thing is that some of the other avi files i've downloaded since this problem began will not open with divx [the default] OR wmp.  they'll only open with quicktime, which seems odd to me--and i rarely use quicktime anyway. that is another reason i reinstalled divx.  any advice, ye who know far more than i???
thanks in advance--
