It may just be a software issue but have you guys encountered this recently? Woke up my system from sleep but it kept on bringing up the open apps like the F3 button was stuck. And when I tried to click on the links on Macrumors, it automatically added it to the reading list (maybe mavericks thinks shift button is depressed?). In addition, when I woke up the system for sleep, even though I have the log in screen disable, it prompted for my password and the top right hand corner stated safe mode in red. When I restarted, everything went back to normal. I'm just worried it may happen again or may get worse. Please help.
