I have used Eclipse 3.0.2 and VE 1.0.2 for a while. I use a base class
inheriting Composite to have a simple OO-design. After upgrading to
Eclipse 3.1 and VE 1.1 are the final classes (implementing the base class)
viewed in a wrong way (all components are in the upper left corner). Why
is is so? And is there a simple way to solve this issue by rewriting some
part of the code in the example?
Example:
In the example is Simple not viewed correct.

}

while (!simple.sShell.isDisposed()) {
if (!display.readAndDispatch())

}
