New Password Textbox Position Not Normal - Moving To Left Or Right

The second textbox will go a liiitle to the left or a liiitle to the right, compared with the other 2 textboxes. What is wrong? Should i use absolute positioning? it's just a pixel farther.I'm about to break the keyboard here

Code:

<div>
<asp:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0">
<asp:TabPanel ID="TabPanel1" runat="server" HeaderText="TabPanel1">
<HeaderTemplate>Change Password</HeaderTemplate>
<ContentTemplate>
<asp:Label ID="Label1" runat="server"></asp:Label>
<br />
<asp:Button ID="Button1" runat="server" Text="Button" CausesValidation="False"
Visible="False" />
<br />
<asp:Label ID="Label2" runat="server" Text="Change Password:"></asp:
<asp:Label ID="Labelmessages" runat="server" BackColor="Aqua"></asp:Label>
<br />
<br />
<asp:Label ID="Label3" runat="server" Text="Old Password:"></asp:Label>
<asp:TextBox ID="TextBoxoldpass" runat="server"
TextMode="Password"></asp:TextBox>
<br />
<asp:Label ID="Label4" runat="server" Text="New Password:"></asp:Label>
<asp:TextBox ID="TextBoxnewpass" runat="server"
MaxLength="20" TextMode="Password"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="Password short"
ControlToValidate="TextBoxnewpass" ValidationExpression="^.{7,21}$"></asp:RegularExpressionValidator>
<br />
<asp:Label ID="Label5" runat="server" Text="Retype Password:"></asp:Label>
<asp:TextBox ID="TextBoxretypepass" runat="server"
MaxLength="20" TextMode="Password"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ErrorMessage="Password short"
ControlToValidate="TextBoxretypepass" ValidationExpression="^.{7,21}$"></asp:RegularExpressionValidator>
<br />
<asp:CompareValidator ID="CompareValidator1"
Runat="server" Text="Passwords do not match!"
ControlToValidate="TextBoxnewpass"
ControlToCompare="TextBoxretypepass"></asp:CompareValidator>
<br />
<asp:Button ID="ButtonPassSubmit" runat="server" Text="Submit"
OnClientClick="return confirm('Try to change password?');"/>
</ContentTemplate>
</asp:TabPanel>
<asp:TabPanel ID="TabPanel2" runat="server" HeaderText="TabPanel2">
<HeaderTemplate>Send us email</HeaderTemplate>
</asp:TabPanel>
</asp:TabContainer>
</div>

Edit, when tested absolute positioning the textbox got bigger(!!!) and in mozilla it was on the wrong side.
