Sooner or later software went discontinued.... I did that when I lost source that time (resently I did got it again, but wont touch it).
There is a bug in SK-Jukebox 4.XX I heard around song skip on some machines. If you dosen't need vidoes, go for version 3.0, which should been pretty stable as it are. I would like to if/when he dedicated to release the source, so these few remaining bugs could been fixed by anyone. Here I wont to due, since Im do not use Visual Basic, but BlitzMax instead.
There is a bug in Arcade Music Box too, where the volume do not change as it should. Here VolumeTray or such utility can workaround that bug, so no big issue (and have description that on my homepage).
Now Im trying to port MultiJuke to Linux, since all others software to Linux is webbased. It would been fine to have a fullscreen app to Linux as well. I guess MultiJuke would been the only chooise for a fullscreen applications for Linux, when it got released. I hope so that software is the best chooise, if you won't pay for Windows. I do not plan to create a video jukebox (no video support in BlitzMax).
