> Here's my problem : I have a main stack calling a modal stack that displays information in real time while some client / server dialog is running. When the modal stack opens, it is located at the loc of the main stack. But if the user moves the main stack, the modal stack stays at the same place, and I would like it to move accordingly and remain at the loc of the main stack, no matter where the user moves the main stack.

usually you could check the "movestack" message, but I'm not sure if the MODAL stack 
will not block any actions? Can't you use a "system window" instaed if that is the problem?
