I somehow decided to use the menu File/open to open a file. It asked me to backup and open the other company file. I logged in and work as normal. At the end I am stuck with a library browser screen and a command centre screen. I can't close the command centre screen but clicke the X on the top right or using alt-F4
When I click on the menu or the library browser, all I get is a warning ding and nothing happens.
Eventually I couldn't back up or close. I have to use the task manager to terminate. A bit scary , hope I haven't lost data
Screen shot attached.
Any idea what is happening?
regards
Basil
