I save my project files always in the pictures directory.
To test my skins I have several project files in the same picture directory:
Three files to test my FancyBox skin: Terschelling_FB.jap, Terschelling_FB2.jap, Terschelling_FB3.jap, a PhotoSwipe.jap file for my PhotoSwipe skin and a file SS4_VarThumbsPerRow_jalbumnet.jap for my Slide Show 4 skin.
If I open jAlbum with project file Terschelling_FB.jap and make and upload this project, you see the layout as shown in screen shot Terschelling_FB, which is OK.
Next I open via the file menu project file Terschelling_FB2.jap. Now you see the first bug:
Nothing changes in the left panel, project Terschelling_FB is still indicated as the active project.
If you click the button to show the published album. You see the 2nd bug:
The published album of project Terschelling_FB is shown instead of the expected previously published album of project Terschelling_FB2.
