hmm ok i went to files-settings-connection settings and selected passive mode .
then i tried to get a file list of a user and i got it . then i tried some other but it came connecting . . . . and i tried to get file list of a user with 0 bytes and i got it . ..
so result was i got 3 file list and 5,6 connection was closed ..hmm could this be because other users are also viewing his/hers files ?
could my net connection speed affect this in any way ?
my speed is just 749kbps
and thanks a lot for helping me :)
