The old version of FlashFXP failed to connect when PASV mode did not work. The new version automatically retries in PORT mode when this failure occurs. From what I understand FlashFXP should remember this and not try PASV connections again when this has happened but I have seen a few session logs where this is not the case. This whole try/fail/retry takes several seconds for each file/listing. You can stop this from occurring by unchecking "use passive mode" in the site manager for the sites Option tab.
If you have a session log of this occurring please send it to
support@inicom.net so we can document it.
