I have Office Enterprise 2007 installed, running under Windows 7. Without any apparent reason Word will not open, that is the opening screen will briefly flash up, and the only other action is that I can view the open page from the task bar (in a very small window), indicating that the app has opened, but is not displayed on screen. All other Office Applications work normally. I have created a second user ID, and have found that the app will now work. In my original user ID I have administrative privileges, so there should be no reason for this malfunction. I have also run the repair function from the original install disc, to no avail. Also done HHD checks, Virus and Malware scans, no change. Any views on the subject would be most appreciated.

It looks like you have moved the Window for Word off your screen. This is easy to do when you have multiple monitors. Possible with only one. What happens if you right-click on the TaskBar Icon and tell it to maximize? to cascade?

Thank you for your help and support, I have solved the problem. I DO know what happened, but I do NOT know how it happened. I am utilising a second monitor, which is only switched on when needed, that is when I am working in an app which requires reference to other files, which I then place on monitor 2. I did NOT use this facility when the problem first occurred, and it was only by chance that monitor 2 was switched on and all was revealed. When Word was shut down from this monitor and I returned to monitor 1 everything functioned as normal. I am grateful for the input that I received, and only hope that one day I may be able to contribute to solve another members problems
