SIMGallery on JSN Epic templates: loading problems

There are several loading problems appears after installing the newest SIMG:
After logging in on Latest Albums page:
* if you mouse over the Profile's name the profile bubble appears BUT after the mouse is pulled away the Profile's name disappears
* if you click on the "Create album" or on the "Video" buttons the screen get dark and there is no way to control or upload
* "Select Category" button doesn't work however there is one cat. installed.
* these happen also on CB profile
I suspect SIMG encounter with Sun framework? I also tested on a Gantry-based site and that works well.
