    [red]Hi mister oil (joke!),

    You got some poor english writing there anyway, but never mind - I can dig it !!
    For a Surinamese guy like me, it sometimes also is a bit of struggle with technical english words but we'll get there won't we??

    Ok, first you need to write a VB (Vertical Blank) routine (= something like a global interrupt service routine) and than point your mouse display routine to it.
    Your mouse display routine have to be part of every VB (run cycle) so it can be display smoothly on any gfx video mode screen you like to configure.
    I'm sure that this will do the trick !! (It works for me so...)

    Yours,
