This is odd: panning works in the preview generated by jAlbum. But not in either Chrome or Firefox, whether hosted on my PC at 127.0.0.1 or on my website. See this example of the problem . Click the globe icon at the bottom.
Ah, I know what's doing that, and it's a skin-specific thing. I'm using a very simple "swipe" script on the pages in the skin, including the map page. So, you can swipe to return from the map. But that script is intercepting and disabling the panning functionality of Google maps.
The simple fix is to get rid of the swiping ability on the map page, which is of only limited utility. I'll fix it in the next release. In the meantime, try opening the skin directory - Tools, Open directories, Skin directory - and replacing maps.htt with the attached version. Let me know if that's better-behaved.
