Or pretend that you are working on your computer, and try to open something...it looks like it opened, but I can't find it in the toolbar, or on any screen...
My computer is broken. I try to open this file and it doesn't come up!!!
Well...what may be happening, is that the default location settings are set to have it come up on another screen...and that screen isn't plugged in, so the computer is sending it to that same location on your current screen.
This is done by making a bitmap on the cyber world, and certain objects and interactions exist beyond your ability to interact with them in real life...even though it may appear you are double clicking an "icon".
Along came a spyder...no. A mouse. Someone decided the user of a computer could be aided by inventing a tracking icon which could be used to select a visual interface (called a "gooey"--later to be known as an ICON--not to be confused with ICONV...)
THE FIX:
First try reopening the object, and right afterwards hit ALT+M
this is the command for moving an object, and will center the object on the cursor.
If you are unlucky and it doesn't recenter on the cursor where you can see it...you can try to move it with the arrow keys...but this may cause more damage...because you don't know where it is, so you may end up moving it further out of the display...)
THE HARDER FIX:
In this case, here is the "tech-y" fix:
Your defaults can be reset in your new favorite tool the "Registry Editor"!!!!!
If you don't have any idea what that is, then go tell your wife you have an affair, and that you must confess your love for another and that her name is REGISTRY EDITOR.
Hit WINDOWS KEY
Type: REGEDIT
Navigation:
HKEY_CURRENT_USER\Software\...your_program_that_has_messed_up_display_defaults\Settings\_name_of_object_in_program_that_wont_display\X-VALUE, Y-VALUE, Z-VALUE
These values can either be negative or extremely positive (which forces the object to appear off of the display bitmap.
Change settings accordingly
