I have a Trust dual scroll mouse which is excellent for moving around docs quickly. I've been using it quite happliy in PM6.52 for years, but in ID CS both wheels only produce vertical movement. Holding down ALT permits horizontal movement (again with both wheels) but on release has toggled vertical movement off. I have to re-toggle Alt to get vertical scroll back.
It's really slowing me up! Any ideas? (OS is XP pro)
