>>>I have a strange problem with a textbox. The textbox is supposed to allow user enter up to 15 alphanumeric characters. This works exactly as designed on my PC (in my IE). But on one customer's PC they can only enter up to 8 characters. And another customer can only enter 1 character. All three of us use IE.
>>>
>>>The code of the textbox is very simple, as following:
>>>

>>><asp:textbox id="txtCostCenter" CssClass="FieldRW" MaxLength="15"
>>>Visible="True" Runat="server"></asp:textbox>

Spaces in the textbox could be put there several ways such as by populating the textbox with data from a character field that contains spaces. Are you assigning a value to the textbox in your code?

I suggested that possibility because it fits the symptoms you described. Have your customer try to move the cursor position over by pressing the right arrow key when they experience the problem. If it moves over a space then there are spaces embeded in the value. You could also have them press the delete key when they can no longer key data which would remove a space and allow them to enter another character.
