Vector Graphics

Hi,

I am having trouble with Vector Graphics between the Mac and Windows. I have an app which I developed on the Mac using Vector Graphics. It took a while, mainly through trial and error to get all the elements on the page positioned where I wanted them. That was OK, it looked really good by the time I have finished.

Then I transferred the file to my Windows version of XOJO on a Parallels virtual drive, and the entire setup fell to pieces!

Is there a secret firstly to being to easily calculate the different .X .Y values between different Objects2D when assembling a page without using trial and error, and secondly, what the differences are between Windows and Macintosh as regards positioning?

Many thanks
