I don't know if you will agree. I'd regard the following behavior as a bug for binding a varchar field to a textbox, no matter in a form (affected by the textbox width) or a grid/browse (affected by the column width).

Run the following code and see how many "i" characters you can enter into each textbox. The maximum number of "i" characters I can enter are (default font Arial,9):
11 in the 1st textbox (bug)
16 in the 2nd textbox (correct)
16 in the 3rd textbox (correct)
21 in the 4th textbox (bug)

When you resize the form, you will find that the numbers will change (1st and 4th textboxes).

Create Cursor T (F1 v(16), F2 c(16), F3 v(16), F4 v(16))
Append Blank
o=Createobject('TestForm')
o.Show(1)

Define Class TestForm as Form
	Add Object txt1 As Textbox With ControlSource='F1', Anchor=10, Width=70
	Add Object txt4 As Textbox With ControlSource='F2', Anchor=10, Width=70, Top=30
	Add Object txt2 As Textbox With ControlSource='F3', Anchor=10, Width=70, Top=60, Maxlength=16
	Add Object txt3 As Textbox With ControlSource='F4', Anchor=10, Width=120, Top=90
EndDefine
