OK, I know I could test this, but just wondered what you lot knew about it. In Blitz Plus any images loaded or created as "dynamic" i.e. on video RAM only would get destroyed if you alt+tab (or windows key etc) from a full-screen game, thus you either a) didn't use them or b) reloaded/redrew them when resume was detected after loss of focus. Now I know that Max ONLY uses dynamic images (unless the video card runs out of RAM I guess) so does alt+tab still present a problem? Thanks.
