This issue tracker is for sigplus version series 1.5.x, whereas your question 
(bug report) relates to sigplus 1.4.x.

For contact information regarding sigplus 1.4.x, please check out the sigplus 
support page: <http://hunyadi.info.hu/levente/en/sigplus/support>.

As for the specific issue you are reporting, you should check the CSS z-index 
of your menu items and that of the lightbox pop-up window. Chances are that the 
z-index of the top menu is so extremely high that the browser displays it on 
top of the lightbox pop-up window. Reducing the z-index value for the menu 
(most likely in a template style-sheet file) or increasing the z-index for the 
lightbox pop-up window (in "boxplus.css" and "boxplus.min.css") should solve 
the problem. For more detailed instructions, please use the sigplus support 
mailing list. Thank you.
