dialog box width

[Robb]

Hey all,
I hope someone can help me fix what seems to be an easy problem I'm having with a dialog box. When someone wants to plot a drawing, a dialog box pops up with a few radio buttons and an edit box. I added a note below the radio buttons but that increases the width of the box with blank space to the right. I've tried a few things but nothing seems to make a difference. I am running ACAD2000. Here is the code and thank you in advance for the help.

plotbill : dialog {
label = "Plotbill";
fixed_width = true;
width = 10;
spacer_1;
: radio_column
{
label = "Plot size";
key = "plotsize";
alignment = centered;
fixed_width = true;
: radio_button
{
label = "A size";
key = "b size";
}
: radio_button
{
label = "B size";
key = "B size";
}
: radio_button
{
label = "C size";
key = "C size";
}
: radio_button
{
label = "D size";
key = "D size";
}
: radio_button
{
label = "Sketch (no charge)";
key = "sketch";
}
} //radio_column
spacer_1;

//This is new code

: boxed_column {
label = "Note:";
alignment = centered;
fixed_width=true;
width=10;
//: column {
: text_part
{
label = " If you do not want to charge for";
fixed_width=true;
width = 10;
}
: text_part
{
label = " this plot, pick Sketch or click";
fixed_width=true;
width = 10;
}
: text_part
{
label = " the Cancel button.";
fixed_width=true;
width = 10;
}
: spacer { width = 0; }
// }//column
}//boxed_row

spacer_1;

//End of new code

: row {
alignment = centered;
fixed_width=true;
width=10;
// spacer_1;
: edit_box {
label = "Job No.";
value = "jobnum";
key = "jobno";
edit_width = 10;
edit_limit = 8;
}
}
spacer_1;
ok_cancel;
}
