Hello, I have an MFC VC++ 6.0 application, where I work on for some months. Somehow the appplication window cannot be activated anymore, when iconized (minimized) on the system tray. Left clicking on the minimized appplication icon does nothing anymore. Only right clicking and selecting "restore" on the system menu works. Normally one should be able to toggle with several left clicks beetween the minimized and the restored application window. Does anybody have an idea what the problem could be? Thanks a lot in advance. Mike
