Just installed Logmein on my iMac, works fine but since my daughter is sharing the same iMac under her own user name, I tried to use Parental control to disable her to accidentally turn on Logmein for obvious reason. When I use her name to log in, the Logmein menu bar keeps popping up every 10 second or so saying I was not authourised to use this application nomatter what I do. I tried to go to User control to check but I can't even get there anymore. Every time I tried to unlock changing anything in user control, "system Preference" crashed and ask to send info to apple! Tried reboot but won't work! Finally have to completely unstall Logmein before I can get back to normal..... what wrong?
