Problem with Directory listing (timeout) with version 5.1.4

Directory /07/ has about 2300 files. If I remove 50% of files the directory listing works ok.
I have also tried with the latest version of WinSCP, but same result.

After entering directory and committing "ls", the client asks for credentials (again).

Did you try setting a longer timeout?

Yes. Same result. Timed out.

The weird thing is: directory listing works ok with my laptop (faster computer Windows 7) but not with touch pad (slower Atom processor, Windows 8.1 Update 1)
Both have same version of WinSCP.

Conclusion: The problem is not related to server.

Can you try it first with another FTP client?

Oh, I tried with FileZilla. Timeouts too. Hmm...

Any suggestions? :)

...with Windows cmd line ftp client directory listing works ok. Is this a passive/active ftp problem?

This is resolved!

I disabled F-secure client security 11.51 (latest version) and now it works!

After enabling F-secure again directory listing stops working. The problem is F-secure, as always. Wheeee!
