I'm working with WAG 1.8.2 to create a gallery of about 570 photos that I took a few weeks ago during a vacation. Obviously, that many photos cannot be titled and arranged and such in one session, so I saved a .alb file yesterday after doing preliminary selection, rotation, & arrangement and today have been working on titling & commenting on the pics.
I've noticed that the "Next Photo" and "Previous Photo" choices in the "Photos" menu are greyed-out, and the hotkeys (ALT+Left-Arrow & ALT+Right-Arrow) don't work, either. This makes navigation a bit tricky... As a fellow software developer I noticed that those options are disabled when WAG starts up and I'm bet that the problem is that the code to enable them isn't getting called when an Album is loaded instead of photos added.
In fact, if I go ahead and add (& then delete) another pic, the choices are enabled and the hotkeys work again as well.
This is probably a one-liner fix in the "album opened" code
I love WAG, keep up the good work!
