Nice idea Pradeep ... but thats not actually the affect I am after.

When my app starts I have an MDI Master showing 2 MDI child forms.
The first MDI child form is a bank of buttons in a column down the left hand side.
The second MDI child form is a slim top-to-bottom of MDI master form on the right hand side.
Any buttons pressed from the form on the left then show another MDI child in the space in the middle.
I think this has got to be down to some kind of desktop setting, as mentioned earlier I think.
Its only out a touch, and only on some PC's, but its enough to make these scroll bars appear.
I think my only option is to go back into the project and shrink things a fraction.

Thanks for the input though by everyone ... much appreciated.
