It sounds like you may be running into a pretty common issue. ..

The designer will execute any code found in the constructor and, if IIRC, the Load event.

Simple way to do this without rearranging all your code to guard any code that isn't purely (and I mean purely) layout code with a check to the form or control's DesignMode property...

if(!DesignMode)
{
//your code
}

As Scoregraphic asks are you performing this manipulation within a separate thread?
