image slideshow on top doesn't work correctly between pages

Hi,
using Image Show GK4 module (I suppose the same used by you in live demo University template) with 2 sample images as slides, the first time of page display is correct (full screen and back-displayed in top menu area), but clicking on item of menu, the "effect" is not correct.
So I ask to you also how could I change the color of menu font on top (now is white).

thank you in advance

Hello,

I'm looking on your website, but I cannot understand what is an issue - could you better describe it?

Sorry,
I've removed the module Image Show GK4 from the other pages (excluded the home) and the problem is not showed in this moment.
I suppose that your demo live use the image slideshow in the home, and then set the principal one slided as background image in the other pages...is correct?

thank you

For using the Image Show like on the frontpage please add the "frontpage" page suffix in the template settings under the features tab.

thank you for your promptly reply.
I've tried to setup this suffix in this way:
Option: gk-is-1 - frontpage set on bottom section of "suffix for pages"

"gk-is-1" is the ID of Image Show but anyway it doesn't work.

sorry

No:

please add the "frontpage" page suffix in the template settings under the features tab

It's ok?
thank you in advance

No - it is wrong - ItemID/Option is connected with menu - you have to specify a menu item ID (ItemID) or component name (i.e. com_content or com_k2).
