Newbie query for " mouse clicking "

[Ashim Kapoor]

Hello everyone,

I am kinda new to Ubuntu, here is my MOST important query.

Sometimes, for example, when I minimize a window by clicking on the
taskbar at the bottom of the screen the mouse clicks a couple of time
" on its own " and I see windows flashing by. How can I prevent this ?

Also sometimes I see 2 arrows in the middle of the screen flash by
when my mouse is on the edge of the screen ? What is that ?

Lovely people, please explain.

God bless.

Ashim. : )
