Hello I have a large project that i bult with windows forms. When I drag a form on my screen it will move with no problem. When part of the form is overlaping the edge of my monitor and i try to drag it , the form will shutter when its moving. It moves as if it is partially stuck to its last position. I could only imagen it being somthing to do with the textures i added to the form componants properties and the way it is drawn when being dragged in this sertine way. When i remove all textures from my form it does not have the jerky drag when i move the form. Could i use another image type to solve this? thanks for any help i cant have this ruin my large project. thanks again.

From you post I'm guessing that your app is a .NET winForms application.
If so, have you tried enabling the double buffering property for the form.
