With tersus 1.3.31 and IE7 i'm having the strangest problem. If i open a pop-in, the window behind my current IE7 window is showed. The focus however stays on the original IE7 window.
Steps to reproduce:
Create a button with a pop-in in it.
click the button.
With the previous Tersus versions i didn't have this problem.
For best results, use the Firefox browser..
