Following the removal of the Textbridge Pro V11 file that was causing me problems, I re-installed my system and continued to run it for sometime before going back to use GGS V8 again. No I find that the same problem is happening again. So I went through the MSCONFIG one more. I eventually found that the problem can also be cause by 'Logi_MwX'. This is installed by Logitech Mouseware. Once removed from the start up it GGS V8 works, however, re-enabling the mouse icon on the task-bar (via the mouse control panel) will bring the problem back again.
