Changes in FlashFXP v4.1.4.1664 @ 10/28/2011:
    * Fixed upload performance issue, after lots of testing and research I have determined that the problem is related to windows "Receive Window Auto-Tuning Level" setting. If you experience a slow down in this release vs previous releases please let me know via the forums.
    * Fixed custom command token %f when executing a command via the FTP search dialog. It was returning the path + filename instead of just the filename. (bug #582)
    * Fixed custom command token %c to correctly handle multiple commands separated by CR/LF.
    * Fixed the Active Edits dialog would automatically appear after restoring the main window, this issue only appeared on versions of windows prior to Vista.
    * Fixed auto reconnect on remote server move folder/file, the connection was restored but the operation was not executed if the main window did not have focus. (Bug #586)
    * Fixed the "swap panes" feature wasn't swapping the text shown on the status-bar. (Bug #587)
    * Fixed defect when performing a custom command after a loss of connection (i.e idle timeout), The connection is restored but the command wasn't always sent. (Bug #585)
    * Improved SFTP upload speed on OpenSSH servers.
    * Improved command line switch parser. (bug #594)
