Mouse problemsFollow

Hi everyone -- I have been having a terrible time with my mouse not letting go of stuff in my house or anywhere indoors where you can let go of or place something. This is a new problem for this mouse I have had and used for over a year at least. I have never had any problems with it before. When I pick something up in my house to move it or set it down, my mouse won't do it. I actually have to cold reboot my machine to get out of my house ( keyboard won't work either when this happens ).... I have tried everything I can think of to fix this problem including writing to sony, with no answer or help...
I have a Logitech Cordless Click Plus mouse and keyboard. I have updated all my drivers, uninstalled and reinstalled drivers -
Could someone please HELP me -- I have collected so much stuff I can't put into my house my bank is full!!!!
Thanks so much

thank you for reply - have done that (changed batteries ) -- did it again just in case -- didn't work. I have used a couple of other mice with usb conections just in case it had something to do with my cordless with no help there either. Same thing happens with any mouse I use. Could it be something in the options in the game I might have clicked on by accident?? This is the most frustrating thing ever!!!!
