RadAsm 3, resource editor problem

[minor28]

I have started to use RadASM 3 and are wondering why the resource editor changes old dialogs values ​​of height, width, etc.

For example a dialog created in RadAsm 2: Height=388, Left=10, Top=10 and Width=523, aspect ratio=0.742

Importing to RadAsm 3 changes the values in the property window  and the resource file to: Height=225, Left=6, Top=6 and Width=344, aspect ratio=0.654

Even the aspect ratio is not equal.

With winspy I can see RadAsm 2 dialog=522x388 and RadAsm 3 dialog=522x382

Can anyone explain that to me?
