Have been using the SIG plugin on a Joomla 1.5 site for a while now, and am in the process of moving everything over to J2.5 now. I have just installed the SIG plugin and everything works fine in IE, however Firefox has a bit of an issue!
When you load a picture, it shows fine and you can hover over Next and Previous fine, but if you click one of them, on the next picture if you hover over Next or Previous again (it's opposite, so if you click Previous, and hover over Next) you get a blue box show up (see attached image).
Tried a couple different PC's and it works fine in IE. Hosting on localhost at the moment so can't post a link to it but I haven't made any changes so I assume this will affect all installations.
Tried looking at the CSS of the box when it happens, but there's no mention of any sort of blue box in there!
Thanks for the awesome plugin - I'm not picking another plugin even with this small fault!
