Okay guys, here's a tricky one. I'm running 10.10 on my pc but i've had this issue for some time now.I'm having strange issues with the mouse. What happens is when I get into Ubuntu, I can click anything, but as soon as I click something to open a window, run a program, I can no longer click anything EXCEPT the last thing I clicked. When I right click the last thing I clicked, it allows me to click everything normally, but only until I open something new. So for example I'll click the email icon on docky to open up my email client, which opens but is unresponsive until I right click docky. Then if I open an attatchment, I must also right click the MENU bar on my email client. Sometimes it also works if I simply right click on the newly opened window. I have tried this mith mutiple mice and still the same issue.
