New packages generated (links in first post). Version is 1.2 now.

Performance increased by eliminating unneeded world-collision animation.
Mouse glitchiness completely gone.
Icon transparency fixed.

Some levels will still be slow (those with alot of animated actors), but performance is noticably improved on many levels. Along with mouseglitch fix this will raise the number of playable levels to nearly all of them (provided you care to invest brainpower in any particular one).

The performance boost of 2008 (70mhz) helps as well but it is very playable on both.
