After rebooting I noticed that a number of the Icons in the menus had gone missing.  For instance under Graphics the icon is there for Picasa and Open Office .org Drawing, but not Document viewer and F-Spot viewer.<o:p></o:p> <o:p> </o:p> When I opened Chrome the little tab icons for closing and adding another tab (x and +) were replaced by a red square. Firefox is not affected and whilst I have not tried every other piece of software. This problem does not seem to affect any other programs.  The vid driver is Nvidia accelerated graphics driver (version current)<o:p></o:p> <o:p> </o:p> Whilst I have some knowledge of using Terminal I have mostly used the easy way of adding program and trouble shooting.  The computer also has Win 7 and this works perfectly so probably not a hardware issue.<o:p></o:p> <o:p> </o:p> Any ideas?<o:p></o:p> <o:p> </o:p> Regards<o:p></o:p> <o:p> </o:p> Neville<o:p></o:p> <o:p> </o:p> </div> </body> </html>
