Greetings,

I updated to 1.8f and encountered a bug when mousing over one of my alts (upper left quarter of screen 2) : after a few clicks, the mouse would switch to Camera rotation, making the screen spinning around and impossible to click anywhere in that client. Mouse would move out to other clients but stay in Cam rotation for that client.
I had to cold-close the client through Vista bottom tab as the ing menu couldn't be clicked on with mouse.

Closed all 5 clients and KC, relaunched : same bug.

Closed all 5 clients and KC, rebooted PC, relaunched : same bug

Reversed to 1.8e : bug gone

I can't tell what's the cause but it happened with 1.8f and not with 1.8e.

One cosmetic difference I noticed about mouse over : when passing from one client to another, the mouse would do a very quick pause at the border under 1.8e.
With 1.8f, this pause happened about 1cm from border (on a 22" screen) but pause duration seemed the same.
