Basic Support? "Nexr Picture", "play no wmv-files"

[Mic]

Hi,

i have installed the new Version 1.97.

1.
Now PageUp and PageDown doesn't work to show the previus or next picture in the actual folder.
How can i activate PageUp and PageDown?

--- Edit: I have found the solution: Because my pictures have the extension .jpg (with .jpeg "1." works), i must inscribe in configuration (F12) under Viewer --> files --> "user defined files" the extension jpg. Than i can use PageUp and PageDown to move to previous or next picture!

But if i open a jpg-picture by double click, PageUp and PageDown selects the wmv-videos in the same file folder still. If i go than in "overview-sight" with "Enter" and than back with "Enter" to "one-picture-sight", than wmv-videos do not selected by PageUp and PageDown. This is not a satisfying solution for the following "2.".
Has anyone a solution for "2."?
Edit-End ---


2.
How can i config XnView so, that no wmv-videos selected and played by XnView by PageUp and PageDown in the "one-picture-sight"?


thanks

PS: Please excuse my bad english.
