Hi Bernd,

>I had this idea, too. But how can I make this container sizable?

It's a little bit difficult. In the MouseDown event you have to create a DO WHILE MDOWN() loop and change the size of the container to the position of the mouse. SInce the mouse position is relativ to the form, check out the OBJTOCLIENT() function to properly calculate the width and height property of the container.
