Mouse Double-Clicks on a single click

This was happening on a Dell optiplex 7010 with a N231 mouse.

It may be due to debounce problems inside the switch mechanics or noise from various I/O chips.

But aside from replacing the mouse (not done), use the software referenced in this page

Internet Explorer - Opening URL links shortcuts maximized

You may be able to open IE maximized but a shortcut on a desktop or folder opens in a smaller window, despite various attempts to modify the program, it's settings or registry entries.

Here's the issue, IE has a concept of a first window and a second window, and you must size each, particularly the second windows...as that's the one shortcuts use.

Open a webpage, then from it right click a link and open "In a New Window"..as that will be the second page.  Size it the way you want (usually the best way is drag the corners to fill the screen).  Now go back to the first window and close it.  Then close the second window.

Now, as IE is closed, double click a shortcut on the desktop (or wherever) and viola IE should be maximized.

In some cases, the tricks of holding down a shift or control when closing a window will have had to be used during the setup described above, but overall this technique always works for me (and most recently didn't require shift or control).

Dell Keyboards

Optiplex units come with basic wired USB keyboards

Previously the ones with large/tall keys, and an outer keyboard shaped that fit around the bump downward of the space bar was:SK-8115.
     An additional part number for this keyboard (or one just like it) seen is: RT7D50

Probably the preferred one of the thin variety:
The thinner keys, and a rectangular shape to the entire keyboard is: KB-212B.
For some reason at the Dell site, the KB212 (without B) is $5 less expensive.

Also saw a KB1421, which has fairly tall keys, and the entire keyboard is rectangular.

Very thin and flat keys, and least preferred, though can type "ok" on it
 is KB113P

The Dell keyboard (with med/tall keys) and a volume knob on upper right is: SK-8135

7-8/2016 see a thin-key keyboard with some light blue on certain areas, KB216t coming with Optiplexes.
