I'm running VS2008 and have used SystemParametersInfo to activate "Focus Follows Mouse" and "Do not Raise On Focus." Sadly though, VS2008 (with and without SP1) doesn't honour the "Do not Raise" part and eagerly pushes into the foreground every time the pointer touches its window.
A while ago I complained about that on my blog and posted an example app to set the parameters. Two others also reported having that problem, but they too didn't know how to proceed.
How could I fix/workaround this problem? Anything else I should try?
