Sequoia is moving my windows off the screen
I'm on my Mail app and I want to look at an Excel spreadsheet to complete some details from an email. When I click on the spreadsheet the Mail app window disappears and I have to click on Mail in the dock. When the window comes up the spreadsheet then disappears, and i have to go to finder to retrieve the spreadsheet, and when it comes up the Mail window disappears again! Can anybody help? Thanks
