Hi Klaus, As it works as expected, when you call alert, it sounds like the Dialog simply doesn't refresh/update the layout. Maybe it's due to the Dialog is very complex, and some Events get lost in space. Some thoughts, not sure if it works * Window has a property "layout", an instance of "LayoutManager". * "LayoutManager has a method "layout()" * layout() is only called the first time a Dialog appears. After that layout() has to be called by script, if Dialog is resized, etc. * Maybe it could work, if you call Window.layout.layout() just before the script finishes. Where "Window" is the instance of your dialog. As mentioned, not sure if this helps markus
