just noticed this..
if the screensaver kicks in while an app (launched from kual) is running, when returning.. after pressing power button in case of PW.. some apps resume.. while some return to the kual screen..
some examples:
resumes -- leafpad, CM
returns to kual -- kterm, kindle explorer
looks like the 'non-resuming' apps are still running, though.. when pressing power button again to activate screensaver, these apps show up momentarily..
may be a 'data loss' issue if, say, a file is being edited in vi under kterm..
enlightenment..?
