Annoying Warning PopUp on ScriptCheck

Whenever i have a mistake in my AS and want
to let it be checked by the Compiler i get an
enervating PopUp, telling me there is a mistake, and
i should look it up in the F2-Window.

This is totally annoying.

I thought they might have fixed it now in Flash8
and i found loads of warnings to disable in the presettings,
but neither of 'em turned the compiler warning off :(

Any trick known, to stop this harrassment?

Another problem i got:
When saving a file as "Flash MX 2004",
i can't use the "Save" button anymore.

Save will either save the file as Flash8 or
do nothing.

Any ideas about this?
