Hi Joseph Thanks for taking the time to reply. In answer to some of your questions: * Is the Sony Vaio laptop using latest BIOS version designed for Vista? Answer: Our technological knowledge is limited but we have installed updates notified by Sony. Don't know if any have dealt with BIOS. * Do you have the latest graphics driver for both systems? Answer: Don't know, same principles as above. * Did you upgrade to Office 2007 Service Pack 1? Answer: In the computer records as downloaded 13 December. * Do you have JAWS 9.0.552 update? Answer: Yes * Did you upgrade to Vista Service Pack 1? Answer: We only installed the Vista Home Premium on the PC last night. Service Pack 1 is not yet available for Vista Business, so no for the laptop. * This only happens when Jaws is running. Furthermore the problems are occurring on Microsoft Office Professional 2007 (we are only using Word and outlook) on both computers, on both Vista Business and Vista Home Premium. However since installing Office 2000 Professional on the laptop and using Alt+F4 to exit, as far as we can think there has been no ghost document and no locking. As we only have the Office 2007 on the PC (running Vista Home Premium) at the moment, I am editing with Jaws running in the background and from memory all has been okay to date. I did get a lock of keys once but can't include that experiment as I remember I did have a PowerPoint document and a word document minimised and both on the screen at the same time. We just might be now at a state where the problem no longer exists since adopting the Alt+F4 exit. It will be a wait and see what happens. Thanks again for your input. Do you happen to have the listserv link for the Blind Vista list?
