Problem with Flashfxp connecting through squid http proxy and checkpoint FW-1

[daz_pp]

* FlashFXP: v2.1, build 924, registered
* OS: WinXP
* Running behind NAT/router: Yes , Name: Checkpoint FW-1 Ver. NG FP3
* Running firewall: Yes, Name: Checkpoint FW-1 Ver. NG FP3
* Running Antivirus: Yes, Norton Antivirus
* Network: Other


My checkpoint reports a problem with the ftp command port.
In the log I get it says: Port command ended without a new line

That way my firewall rejects the connection..

I've tried with CuteFTP Pro and it works perfectly

Any hope of getting this fixed in the near future?

Thanks for a good program
