Hail! i've been using this nice plug-in since 1.0BETA and enjoying it.
but now i and my friend have a little problem.since we updated it to 1.1BETA,the resume function doesnt work correct.

i send a file(name- XXX.abc) to my friend,and just cancel it.
then i send the file again,and he receives it as a new file (name -
XXX1.abc).it seems that File Transfer Plus renames the file.

when we used 1.0BETA ,we didnt have a such problem.it was
automatically overwritten.

could you plz tell me how i can fix this?
thanks in advance.
