Because Milkdrop does things related to keyboard input (e.g. preset menu navigation & a few other things), it doesn't generically pass on keyboard presses it receives but doesn't handle to the main window unlike most of the other plug-in windows that WACUP provides.The space key is used by Milkdrop in a long standing action to pick a different preset to render. I get that is at conflict of the usage of space within other changes that WACUP have introduced but I'm not sure about changing the default Milkdrop handling.So I'm not sure what the best approach is to take with this.-dro
