Hi,
I am having a similar problem.
I have a jQuery/css based vertical slide menu, and haveing PowerGallery seems somehow to force all the menu "kept unfolded", where only opened category area menu should be unfolded.
(See: shop_160_covers.php )
I tested with jQuery LightBox (similar effect with PowerGallery, but much simpler) to see if that triggers the same symptom, but it didn't.
(See: shop_054_adptv_test2.php)
I'd like to stick with PowerGallery, as it is easy to use, and it gives me sliding effect that I can not hand-code.
Could you take a look and advice me what to do to keep the menu folded?
Thank you for your help in advance.
Rika
