I did use FrmHideObject() when I wanted to change the text in the label but I don't
use it
anymore, I read something about it & I had the same problem as you have. So, now, I
use
// some code to make sure that labelText is shorter than
// the original string in the label (or cut it)
// ...
FrmGetObjectBounds(frmP,objIndex, &r);
WinEraseRectangle(&r, 0);
FrmCopyLabel(frmP,objID,labelText);
This code works every time for me (different OS version)

When you mention "field", I don't know if you still talk about label or you also talk
about text
field. I use SetTextField(), GetTextField(), FreeTextField() to manipulate text
fields. These
functions are mentioned a lot in Palm books, in this forum and I can send you my code
if you want.
HTH,
