Hi, i am new to autoit, i am learning a lot through the help file and through this forum, recently i notice that some times, when my script is interrupted manually or if the script runs through an accidental infinite loop - and then i try to exit the code by rightclicking the autoit icon on task bar - my computer behaves strange. when i try to right click a file, it behaves as if i am trying to click on an empty space in folder, sometimes the keyboard doesn't work, sometimes when i try to click on a folder, it open the folder multiple times. the only solution is then to do a reboot. please assist. what could have gone wrong here. thanks
