Shift + RMB doesnt work... sometimes

I dont know why this happens but sometimes while working on a model, when I right click and select a vertice, the vertice gets selected, then I click shift and right click another vertice, the second vertice isnt selected. When I release the shift key, the selected vertice is now the second clicked vertice.

I’ve shut down blender, didnt work.
Restarted windows, this worked.

I’ve searched but couldn’t come up with anything on this. Has anyone else experienced this or know whats going on?

Thanks for any help.

Ok, disregard.

You cant play Stronghold Kingdoms while trying to make models, it may cause some graphics/ Video anomalies.

Hehehhee!

If you game a lot, you may have worn out your mouse button.

I know I have worn out a couple of mouse buttons in my day…
