Home Buttons can appear to log user out.

I'm experiencing rather strange behavior on my site.  I'm using the Graphix template.

I currently have the site set to display the splash screen on all pages.

When a user logs in, if he presses either the home button in breadcrumbs, or the home button on the main menu - then immediately presses the other home button (main menu or breadcrumb, which ever was not pressed first) - then the site appears to log him out.  Join or Login will again appear in the header.

If you then click on the join/login button, the user is immediately logged in (avatar reappears) but the main background resizes to match the body column.  Clicking on any other menu button resizes the page back to normal.

Has anyone else seen this behavior?  I'm using Chrome ver 56 / 64 bit.  While this can be lived with and probably won't happen too often with users, it appears to be a bug that should be addressed.  If I have time to track it down some day, I'll update this post. 

I'm not familiar with the Graphix template, but I've used all the supplied templates plus another commercial one. The splash screen being on every page shouldn't cause the problem, thus I'm inclined to think it's a template issue. The Graphix mob should have their own forum somewhere and I suggest you contact them. 

Thanks.  I did try it without the splash screen  on every page and it makes no difference to the behavior.  I'll contact graphix.
