No more object selection possible. Only polygons...

Hi all,

trying to block an arena shooter level, and I don’t understand why I am now unable to select just the single object… Everytime I click to select, I am in edition mode, and only polygon is selected…
In that situation I can’t apply a material on the entire object, I am supposed to apply it polygon by polygon (before that i drag a material on the object and done…)

I think it happened after i did a BSP editing of some objects…

Please help me understand why or what I did wrong, and how to comme back to a simple object selection.

Thanks!

Pierre, France.
