yeah, i'm looking at the doc file for the version i am using. here is what it says

DynAmpWinampStartNormal
Default = false
On opening, the player will remain on screen. If this is not set, the
player defaults to minimizing when run. (This works only with DynAmp bang
commands, not running the player through any other method.)
