I want to purchase the Pro version. I am testing the free version at the moment. When I open a gallery in lightbox I get the first picture OK. When I click either the "next" or "prev" and then after that pic. is displayed, moving the mouse off the "next" or "prev" area (anywhere on the screen) that half of the picture disappears and is replaced with a colored block. If I move the mouse back over the area the full image is restored.

Any advice appreciated.

Could you provide a link to your site?

Also because the problem you are facing is with SIG and not with SIG Pro this topic is moved to the appropriate section of the forum.

If you like to purchase the Pro version please do snd check if the problem remains. With the Pro version it's more likely that you won't have a problem while it's a little different with the free version.

Well I've just bought the Pro version and the problem is the same.

Please move post back to Pro forum.

Advice appreciated.

As Yiota said, please provide us with a url... Hope you fully uninstall SIG before install SIG Pro...

Please move this post to Pro forum as this is a bought item now.

I am testing in Firefox but the problem is also present in Opera. The hover problem does not seem to be there in IE7/8 or Safari.

OK, thanks. The URL is www.acdorchester.org.uk/memories/196-galleries.html. Please note I am making this menu item temporarily "Memories" public to enable you to see this. The sig gallery if the first on the page (the other galleries are BK-thumb (multithumb) but that plugin is disabled).

The images are affected by this styling from your layout.css

a:hover, a:active, a:focus {
background:#B9C0F7 none repeat scroll 0 0;
color:#0B1560;
text-decoration:none;}

If you remove background:#B9C0F7 none repeat scroll 0 0; you will not have any problem. Differently you can add an id -that does not affect FPSS styling-in front of the a element so as to solve the conflict.

It solved by adding Background:none; to slimbox.css line: #lbPrevLink, #lbNextLink{display:block;position:absolute;top:0;width:50%;outline:none;background:none;}.

Can this file be moved (from the popup_engines/mootools_slimbox/css folder) to the templates area like the jw_sigpro folder? So that when I upgrade it won't change.

No...But you can keep a copy of this file in your pc.

2011 install of SIG Pro in Joomla 1.7, astonished that I had to spend time finding this fix and applying it manually, given that  the issue of the overlay misbehaviour has been cropping up since 2008. Thankful nevertheless that the solution was available to find.

This was a css conflict with ones template. The plugin works just fine.
