Default behavior for animated BMP

[Yury]

My XnView is set for opening files in View mode on doubleclick/enter.

I have some animated BMPs, and i know, that XnView is aware of this format, because after doubleclicking first file is displayed as animated.
But when browsing thru the folder containing few such files, at some point animation display breaks, and files become displayed as solid BMP consisting of all its frames (well, in fact, i guess, it is how it really looks like if not taking to attention its 'animationess'). Using Reopen command makes them be animated again.

So how exactly XnView is meant to display animated BMP - as a whole or as animation?

I'm terribly sorry for usually posting of such a small problems. Though i do not lose hope to find someday a serious exploitable bug in XnView and become famous. J/k.

Here are some animated BMP http://www.sendspace.com/file/i0gthe
