I have a small but annoying issue with the DVBViewer latest version and I wonder if it can be reproduced in other systems and maybe correct somehow. When the video is played in a small window ("always on top" enabled) I can adjust volume simply by placing the mouse cursor over this window and use mouse wheel. No need to click the window to give it focus.
But for an unknown reason I can't do this for scrolling through the channels in popup channel list (left sided in my case). The popup list is triggered correctly when the cursor is near the left edge of the window (once again no focus needed) but scrolling is not working.
I have to put focus on DVBViewer window first by clicking on it. And only then scrolling through channels work.
To sum up I can volume up or down without focusing the window but I have to focus it to scroll through channels in popup channel list.
Small but quite annoying I have to say.
