  • Font_ScanString, icon widths not sticking

    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.

    You are using the 'current font handle' (R1=0) so if something has changed font (like mobing an icon) the results will differ.
