AutoScaleMode.Font crashes program

[Paul]

Windows Forms, .net 2.0, vs2005, xp pro.

Setting AutoScaleMode.Font (or Dpi) on my main form crashes my program on some computers. If I set it to None or Inherit program runs ok. It's a very simple form with a picturebox, combobox and a slider.

..net 1.1 is not be installed on at least one of the problem computers. Is 1.1 sometimes required for 2.0 apps to run correctly?

Error:

Still not working. Anyone have any ideas? The code is mostly from the AlphaBlend demo on CodeProject. The program runs on the development system every time. But it fails on a new XP install with only .net 2.0 installed. Kind of looks like a bug in the framework.

//
// Form1
//
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(755, 405);
this.Controls.Add(this.panel1);
this.Controls.Add(this.statusStrip1);
this.Controls.Add(this.pictureBox1);
this.MaximizeBox = false;
this.MinimizeBox = false;
this.Name = "Form1";
this.Text = "Alpha Blend Demo";
this.Load += new System.EventHandler(this.Form1_Load);
