Here it goes, no big words needed:

- I can't merge two (or more) meshes together. The programme doesn't let me select more than one object.

- When I select a polygon/point/edge, the selection is still there when I have unselected the object and goes back to it. Do you get what I mean? It's late where I live, so I might be too tired to make any sense. If you don't get what I mean, I could probably do a simple .GIF animation where I show the problem.

Also; Note that I personally never changed any settings. They just appeared from nowhere.

Thanks in advance and cookies to everyone.

hold shift and select next component

and you can set File->Preferences->Tools->Selection - Extended Component Selection - check on and then previous component will stay selected without holding shift

middle mouse for unselect
