When working with Domino Designer it takes a whole era to open an application when there are multiple entries in the list of applications.
Also when I open or close an application this results in a permanent flickering and erratic behaviour of the applications list pane and its scrollbar. The same applies on changing working sets.
After an application finally revealed its desing secrets, still the flickering and bouncing remains for a while. Meanwhile, if you click on an element of the opened application it opens everything but the clicked element. You need to wait until the bouncing and flickering ends before you can select an element to work on.
