Compiled Client (PC or WebPlayer) Crash On Application Quit

[Yukichu]

Unity 4.3.4f1
NGUI 3.4.6 or thereabouts

Close the window for a webplayer or PC compiled player, and it crashes.  Webplayer doesn't tell me much in the error log, but the PC output_log.txt says:

NullReferenceException
  at (wrapper managed-to-native) UnityEngine.Component:InternalGetGameObject ()
  at UnityEngine.Component.get_gameObject () [0x00000] in <filename unknown>:0
  at UIDrawCall.ClearAll () [0x0002c] in C:\repositories\daedalimperium\DaedalImperium\Assets\NGUI\Scripts\Internal\UIDrawCall.cs:664

(Filename: C Line: 0)

I looked at that line in UIDrawCall.cs and it's already checking if the application is playing, so I have no idea.  I am closing the application by hitting the little X that closes like every window.  I've already read about how application.quit() sometimes fails (or used to), but I'm not trying to close the program via script...

Any insight would be great.

You need to update to the latest version. This was already fixed.

I must've missed it.  Will update, sorry for not being at the latest version.  Probably should've done that before posting.

Just I have to manually change a bunch of stuff every time I update

Anyhow, thanks for letting me know, will do.
