Default Socks5 + implicit SSL causes infinite loop (100% cpu) on upload

I thought it would be best to post in here before I open up a bug ticket because it just may be a user error with my settings.

Ok first off basic info:
client: FlashFXP 3.4 build 1145 unreg
OS: Windows XP Pro SP2 (with current updates)
Router: Linksys WRT54GS

Code:

Once it reaches that point, it locks up and starts cycling 95-100% cpu usage.

I edited out the actual ftp and Socks5 proxy for my own privacy. I was able to upload the files to ftp ok with Filezilla but that client has issues with corrupting the uploaded data. If there is any more info I can provide, please let me know.

edit: I resolved it. I disabled Compression (MODE Z) for uploads. But I think this is a bug or some conflict with FTP? Program shouldn't be locking up.

I believe this issue has been resolved in our current beta release. Hopefully it will be released later tonight. It will be build 1170.
