Zend Studio 3.5.2 and file corruption with FTP?

Hi all,

I'm using Zend Studio 3.5.2 on a Win2000 machine to develop PHP code on
a RedHat Enterprise Linux server and I'm using Secure FTP to move the
files back and forth between the server and Zend Studios edit buffer.
This works fine and hasn't been a problem. However, last week the PHP
files I was working on were corrupted and turned into 512 byte long
files that contained nothing but a single low ascii control code
repeated 512 times. Someone suggested to me this could be a problem
caused by FTP. Has anyone else had this proble or experienced anything
like this? Has anyone got any insight on this?

Thanks in advance,
Doug
