Wireshark 1.4.0 (32-bit)

What's new in this version:

# The following bugs have been fixed:
* Update time display in background. (Bug 1275)
* Wireshark is unresponsive when capturing from named pipes on Windows. (Bug 1759)
* Tshark returns 0 even with an invalid interface or capture filter. (Bug 4735) 

# New and Updated Features
* The packet list internals have been rewritten and are now more efficient.
* Columns are easier to use. You can add a protocol field as a column by right-clicking on its packet detail item, and you can adjust some column preferences by right-clicking the column header.
* Preliminary Python scripting support has been added.
* Many memory leaks have been fixed. 
* Wireshark 1.4 does not support Windows 2000. Please use Wireshark 1.2 or 1.0 on those systems.
* Packets can now be ignored (excluded from dissection), similar to the way they can be marked.
* Manual IP address resolution is now supported.
* Columns with seconds can now be displayed as hours, minutes and seconds.
* You can now set the capture buffer size on UNIX and Linux if you have libpcap 1.0.0 or greater.
* TShark no longer needs elevated privileges on UNIX or Linux to list interfaces. Only dumpcap requires privileges now.
* Wireshark and TShark can enable 802.11 monitor mode directly if you have libpcap 1.0.0 or greater.
* You can play RTP streams directly from the RTP Analysis window.
* Capinfos and editcap now respectively support time order checking and forcing.
* Wireshark now has a "jump to timestamp" command-line option.
* You can open JPEG files directly in Wireshark.
