Filetransfers:
When miranda is RECEIVING:
Everything seems to work. You see a progress bar, it is possible to queue up multiple files. Works for miranda->miranda and utox->miranda.
When miranda is SENDING:
Receiving side sees a progress bar like normal and will generally receive the file just fine.
Sending side sees "request sent, waiting for acceptance" during transfer; no progress bar. At the end, sending side sees "file transfer failed", but the receiving side has the complete file.
