Has anyone else encountered this? I used Spotlight to find a file I needed to work with. So far so good. I found it. I opened it in Excel 2008. Excel looked totally open. I couldn't find the file open anywhere, though, and it wasn't showing up in Mission Control. I then swiped over to Dashboard. There it was, open in dashboard, under my widgets. Quitting and reopening Excel opened it on my desktop properly. I wasn't able to reproduce this. Has anyone else experienced anything like that?
