Can someone tell what's wrong with this, please:

 bbox!0  = 0
 bbox!4  = 0
 bbox!8  = 0
 bbox!12 = 0
 bbox!16 = -1
 SYS "Font_ScanString", 0, text$, &40020, 3000*400, 2500*400, bbox
=bbox!28 / 400

Or this:

 SYS "Font_ScanString", 0, text$, 0, 2500*400, 2000*400 TO ,,,width%
=width% / 400

The icon widths are correct at first, with either method, but then break
down and are shortened, seemingly randomly, when the icons are moved.
