okay i have a acer Laptop

and basically i was asked to get rid of the Menu Thing on the desktop and enable the right click menu

and basically you do that with a command (i dont have the laptop to check what the command was) but it was something like Xfce Desktop , or something

basically NOW what the problem is the Browser Tends to Crash and the right click button ON the laptop seems to have stopped working
yet it doesnt ALWAYS do this.. it did it a few days ago and now its doing it again

could the said command do that damage or is there a fault elsewhere OR is the Laptop damaged
as far as i can tell it hasnt been dropped and its only a few months old not even

thanks for any help
