We recently switched from a Windows PC to an iMac. So far love it, but there is a learning curve! My wife said she could not find the calendar app icon (iCal) - we have both been using it in our respective accounts - I guess it had been awhile since she had used it? Thinking I would solve the problem, I logged onto her account and went into the Applications folder and dragged the iCal icon onto the desktop. Not exactly sure what happened next - my belief is that just by using the application, the iCal icon reappeared on her toolbar - so all is fine again with respect to her being able to launch the program from the toolbar, EXCEPT... the iCal icon that I dragged onto the desktop is still there and I can't get rid of it. If I move it to the trash, but clicking on the iCal icon (the link) in the toolbar won't launch the program - it has to be removed from the trash. I can't put it back into the Application folder - it asks if I want to replace the existing App and I'm afraid we will lose all appointments, etc. that we already input into the program. Please help - I promise I won't do this again!
