Some people reported much slower initial loading of WS 0.99.4 on Windows compared to previous versions. It seems that it stays in the "Init Dissectors" text on the splash screen for about 13 seconds!
As I cannot confirm this on my developer machine, anyone else seeing this or have a clue what's the cause?
Yep. Upgraded from 0.99.3 -> 0.99.4 just now, and the delay shoots up to about 11 seconds.
It might be helpful if someone who's having the problem could download
Process Monitor from
and look for operations that take an unusually long time during
Wireshark's startup.
Thanks for the clue as to how to debug things on Windows.  :-)

Unfortunately, the vast majority of my startup delay happens in between these 2 events (filtered on Process Name==wireshark.exe):
9961	12:10:32.2664940 PM	wireshark.exe	2112	CloseFile	C:\Program Files\Wireshark\wireshark.exe	SUCCESS	
13568	12:11:03.3613993 PM	wireshark.exe	2112	RegOpenKey	HKLM\SYSTEM\CurrentControlSet\Control\ProductOptions	SUCCESS	Desired Access: Read
I was watching my system's time while this was happening and Wireshark 
entered "Init dissectors" around 12:10:32.
I can send a complete log if that might be useful.
