Freezing on loading directory listing

Just noticed this today - connect to a saved ftp site (type doesnt seem to matter)... smartftp takes up 100% cpu on loading the directory listing and just freezes/hangs intermittently.
tried a few different sites - same problem. even after a reboot.
tested with other ftp clients - no issue.
