By near ever, all the systems (Jaguar Panther and now even Tiger) and machines (iMac, iBook, PowerBook, Power PC G4) this (good) product gave me the following problem: control-shift refuses to open the contextual menu of the app itself! I tried even this last version and it functioned the first time and after... no more! The read me is far too simple, some commands like how to shift the position (shift-drag) are simply not mentioned, the preferences are not 'self explaining and no manual is included (tooltips? When? Where? For beginners, Ok, then?)
