Thanks for that guys. I installed the Windows Mobile Center 6 software and now I can install programs onto the device.
Ok, moving on. The IDE on the device works fine, and if I write a new test application on the device then the form appears as you would expect. I dragged a button and a list box onto a new form, and checked the width of the listbox which was about 200px.
So, it seems my problem only occurs when I make an application via the desktop IDE.
To confirm the issue, I made a brand new application using the desktop that simply had a button and a listbox. I've attached a couple of screenshots to this post.
Designer.jpg is the design of the form on the desktop. form_on_axim.jpg is a screen shot taken on the device itself.. you can see how the controls are almost half the size they should be.
Hope that helps.
Thanks!
Andrew.
