http://ubuntuforums.org – Am having a problem with every application that uses dropdown menus or forms that have check boxes. When I mouse click for a drop down menu the menu will open then close immediately when the mouse button is released and will not stay open. I can then get it to stay open by clicking with the mouse several times. Same thing occurs on pages or forms that have check boxes. Most times have to click the box several time for it to saty selected. Also have a great deal of difficulty when trying to copy text from documents as the text will not highlight nor stay higlighted or will highlight part o (Hardware)
