Inaccessible Serial port terrminal

Hello,
I have been messing around with the arduino for a few days now but I have come across a somewhat major proble as of late.Whenever I open a serial connection (serial monitor,serial plotter)The resulting window opens but i cannot access it because whenever i click on it nothing happens.Is this a konown problem that I haven't found a solution for online or did I mess sth up big time?
