Tim, I noticed the following messages in my xsession log (GIT build): TQObject::connect: No such signal KLineEdit::textChanged(const QString&) TQObject::connect: (sender name: 'excludeLineedit') TQObject::connect: (receiver name: 'SMServerConfigDlg') Investigating revealed the errors always appear when I open KControl/TDE Components/Session Manager. Further investigation revealed the likely source is tdebase/kcontrol/smserver/smserverconfigdlg.ui:240: <connection> <sender>excludeLineedit</sender> <signal>textChanged(const QString&amp;)</signal> <--- problematic string? <receiver>SMServerConfigDlg</receiver> <slot>configChanged()</slot> </connection> Should that line be TQString? Further, in all *.ui files, should all occurrences of QString be changed to TQString? Or, is there a build macro that is supposed to be changing those strings to TQString that is not functioning correctly? There are many occurences of QString in many *.ui files in the full source. If these all should be changed could this be the cause of various bugs, such as What's This help tooltips no longer working in KControl? Darrell
