Version: (using KDE 4.3.2) eg Present Windows with 'Show Panels' enabled. Since the panel is apparently untransformed from the normal mode, in Present Windows we expect to be able to use panels normally - eg choose a window using the taskbar. Instead a click just selects the nearest window.
The adding of the setting to present windows would ideally be reverted instead of trying to allow the panel to be clicked. *** This bug has been marked as a duplicate of bug 178913 ***
