Hi all, I have weird problem with Photoshop CS4 under Lion guest system in Parallels 7 everything is running on MacBook Pro on Lion. When I try to use any brush, or marquee, clone or heal tool it looks like the first time I press the mouse button it registers it, but when I move a mouse it stays in place. Mouse pointer moves around the screen ok, it is just the Photoshop brush that stays in place. When using Marquee tool I should be able to click on canvas and drag to resize the marquee. Instead when I click it creates a marquee starting in the left hand upper corner and ending in the point where I clicked (creating a rectangular shape, see picture), Similar behaviour exhibits vector tool (see picture) I have clicked in the left down corner, then in the middle, and in the right upper corner - in theory that should render a straight line, but it creates weird shape instead. Settings: Macbook Pro - 8GB mem, 2.66MHz, Lion Parallels 7 guest system Lion, 3GB mem assigned, Parallels tools installed. The same effect in full screen and in windowed mode. Cheers
