Ok let me explain better.
I select a vertex, nothing happens, select another vertex, the first one becomes selected.
I select a vertex, nothing happens, I move in 3d space, the vertex gets selected.
its like blender is not updating until i do something that makes it do so.
but this happens for as far as i can see everything. even selecting folders to save the file to i have to double click/do another action to get the action i want to actually appear.
Edit: So far it does not do it when i click check boxes, but does when i click drop down menu’s or places to type in. etc. very bizaarre.
not sure if this is blender or my computer.
