This seems rather strange to me and was wondering what the solution is:

If i have a Form (Form1) and add a new item, an AboutBox, to my project (AboutBox1). If I open this Aboutbox from a menuStrip item (Help -> About), the AboutBox always appears in the centre of my form and it doesn't matter where the form is located or what size it is. That's great.

If I have a File -> Open menu item and want to open an OpenFileDialog, it doesn't have the same behaviour. No matter what size or where my form is on the screen the dialog always opens in the same location which I really need to stop it from doing.

Does anyone have answers to why this happens and more importantly - a solution so the OpenFileDialog does what the AboutBox does naturally.
