Thanks for this tip. But wait... this "alpha parameter" , are you saying I can colorize my bitmaps?

edit: or do you just mean I can adjust the transparency (alpha)?

OK.
screen.Drawscaledobject( 620, 230, 2, 2, varr.but_off ) 'good

So the scale params are supposed to be floats, natch but the above works.
Until you add the ( i swear i saw it somewhere - recently documented alpha parameter) then it errors with type mismatch
screen.Drawscaledobject( 620, 230, 2, 2, varr.but_off, &hFFFFFF99 ) 'no good

but when you do it correctly:
screen.Drawscaledobject( 620, 230, 2.0,2.0, varr.but_off, &hFFFFFF99) 'good

Now it flys!
