It allows multiple MDI-like windows. If two windows each containing a listbox are being moved in a way, so that the slider of the listbox of the topmost window is exactly above the listbox of the second window that is below then it is not possible to drag the slider with the mouse. Instead nothing happens. Reproducible: Always Steps to Reproduce: 1. create two listboxes with one being having its slider right over the other 2. try to move the slider with the mouse
A minimal testcase would be great here.
Reproducible: Not Reproducable After a couple of more tries the problem dissapeared. Seems as if this was a strange random hickup.
