Flash Builder Design Issue!

[PapillonGrafix]

This is a very annoying issue that im having. I have had Flash Builder 4 installed since the launch of CS5 and just started to use it. The problem im having is with the designer when constraining an object to the corners of the document.

Whats happens in the object goes off the canvas when constraing it to the right, left and top.

Here is an image of what im talking about.

The issue does not seem to be present  in  FB 4.5 so i cannot give exact reason of the issue.  Anyway you can see that the right alignment value is showing negative number in the text box.  So you can adjust the value to a positive number which is suitable for your requirement
