form.show doesn't show all the content on the form like forms.showdialog

Question

I am currently developing a GUI that helps users pick a test to run for a DUT. The program controls a bunch of lab equipment via visa com drivers and logs the data and determines the final result of the test. All of this works just fine.

The tests have multiple stages and I want the application to show in which stage the program is at a given point of time via a windows form. So I created the following form.

Complete Form

Each textbox represents a stage in a test and when the stage is done, the background turns green. I need to show this form and keep executing the program. So I used object.show(). It only shows partial form like this:

Partial form

It shows the complete form if I use object.showdialog(). But the program won't run till I close the form. How can I fix this problem?

Code:

    partial class TestUpdateFlowChart
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;
    
    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }
