Version: (using KDE Devel) Installed from: Compiled sources Do this; * right click on titlebar * Open 'configure' dialog. * Go to 'Window Specific' tab. * Press 'New' button. * Press 'Detect' button in the dialog that shows. Notice how your cursor changes to the cross-hair. At this point I expect that clicking will do something, like fill in the details in the dialog. What actually happens is that clicks are ignored. Note that pressing escape (twice!) will get you back to your regular session.
