    Hi all,

    Just to throw another iron into the fire, we've had some troubles like what Clive has
    described. Ours weren't just with resizing, they also occurred when the initial form
    appeared. After about a week, we discovered that the font preference order on the
    client mattered considerably. We wound up using 100 point fonts and everything cleared
    up after that. We use Exceed 7.1 on a Windows machine connecting to a Dec Unix machine.

    Hope its as simple as what we eventually found,

    Jim Stegeman
