Menu block dissapears when clicked on views child

Hi,

I'm a bit of a newbe when it comes to drupal but i'm learning everyday..
The issue i'm having is that I have a website with a main-menu (level 1) in the header region and a main-menu(level 2+) in de left-sidebar, both made with the Menu Block module. Both with an active-trail. On a basic page somewhere in the second level I have some views in a block. When I click on a link in a view 'read more', the page i'm going to is the node id and the menu block level 2 is gone included the active trail in the main menu level 1. I made a simple drawing to visualize the problem. On the left side you see how the situation is. On the rightside How I want it !

Perhaps there is a other way to achive a better result. If someone can help me I would be very happy :-)
