FYI, found out a bit more for anyone running into this.
Some plugins cause the issue, some don't: PK, PK sharpner, and GF up to 5.04 do not cause a problem -- and for my workflow the only plugins I use regularly. PK Color 2, and NIK Colorefex cause the problem. As do all the current version of all NIK plugins: the ones for BW, for noise reduction, resizing, and Colorefex 3.
That said, all you have to do to get past the issue is to open something like Colorefex and then close it. The CS4 menu then work fine, and continue to until CS4 is closed. So something is happening as some of the plugins are loaded which is "fixed" when they are opened once -- and you don't have to perform an action, just open and close. So an easy Action that you can run when you open up CS4.
Imagine this is something that is more PS than the plugin makers and will end up being fixed in v11.01
And have to say the more fluid zoom in CS4 (as opposed to having to go to 25%,50%..., etc ) is very useful -- I do have a video card that supports this. Also finding that CS4 is a faster program than CS3 with no changes to hardware, which is surprising given some things I have read. The other new bits seem like nice gadgets (which no doubt have real value for some specific users) that one will rarely if ever actually use -- something like NIKColorefex.
Have also put in in a technical request to Adobe support, and will post anything of value provided.
