This patch does the following:
- the drop-down line selector fits now in the window, even if the window is resized to small sizes
- for these lists a scrollbar is drawn only if necessary
- if the outer window is resized, the drop-down list is resized as well
Hopefully, with the patch, drop down lists stay in their windows. This should remove the bug, that in such oversized lists it was not possible to select items that left the dialog window.
