I got exactly the same pb than the others but i've got a few precisions to make :
First it's a random bug, sometime it works sometime not...
Second the bug doesn't appear un cuteftp pro (never) so it must be fixable.
Last the bug appears more often when using a proxy to make transfers...
That's all for my contribution, ThX for fixing this really shitty bug that makes me go to cuteftp pro
shitty interface....(pleaz fix it, i love Flashfxp)
