Question

I seem to have lost the red, green, and yellow dots that are in the upper left hand corner that close or minimize the page.  How can I get them back?

Answer 1

You may have to try a general OS X troubleshooting process to see if the issue goes away by doing this...
Have you tried: starting the computer in SafeBoot mode, with shift key held down; a login screen should appear after a time, and then the regular desktop. At this point, locate Disk Utility in utilities folder, and run 'repair disk permissions' on the startup volume, usually the name given the hard disk drive as it appears on desktop. After Disk Utility is finished the permissions repair, restart the computer normally.
...The iTunes player has free support only through the duration of the hardware product's complementary or AppleCare extended plan coverages, so though you can download a newer version, that is not the same as free support for an issue. However, the iTunes Store or App Store has a different factor for their product.

There is an iTunes area in Apple Support Community discussions for more topics like this; except for when they involve a hardware product where an OS X is involved. If your computer is NOT a powerPC (an 'intel'-mac) the topic would more naturally need to be posted where that hardware and later supported OS X version topics get seen. So that is why one asks 'on what Mac running what version...' instead of writing four paragraphs in a wide angle reply. The details about your iMac and the OS X say more; without them, more questions arise.
Good luck & happy computing!
