[Ham-Computers] RE: Interesting problem.

[Hsu, Aaron (NBC Universal)]

I see this occur on my computer(s) once in a blue moon...Win95/98/2K/XP - doesn't matter.  It's  a situation where Windows thinks the <ALT> key is being pressed or the <ALT> "bit" is set in Windows' keyboard routine.  Usually, alternately pressing both <ALT> key (a few times) or alternately pressing the <CTRL>, <ALT> and <SHIFT> keys in random order "fixes" the <ALT> key behavior.  As another alternative, taking your hand and pressing a bunch of keys on the *left* side of the keyboard at once often manages the same (don't do this on the right side as you might invoke the <CTRL><ALT><DEL> combination).

I also experience a similar situation with the <SHIFT> key occasinally - Windows thinks the <SHIFT> key is pressed when I move the mouse and it starts highlighting everything on the screen.  Right-clicking and selecting a menu option usually resets this situation.

And, almost daily, I experience a another situation where Windows thinks the LEFT mouse button is pressed when it isn't.  This usually occurs if I'm "left click-dragging" something across another window and the "focus" changes to a different window - in that Window, the mouse behaves as if the left mouse button is pressed, so if the focus in that window was on a scroll bar, then the window scrolls when I move the mouse - if the focus was on some text, it moving the mouse highlights the text.  For reference, this usually only occurs when I'm "multi-tasking" with multiple apps and explorer (Windows, not Internet) windows open.

BTW, "focus" is the term used to describe the program or window that's currently in the foreground.  For example, if you click on a link in e-mail, the Windows usually changes the "focus" from your e-mail to your browser (as soon as it's loaded).

Subject: [Ham-Computers] Interesting problem.

On two different computers, after sitting for random lengths of time, double
clicking on an icon or quick-link brings up the link properties rather than
run the program.

One computer is a 100 MHz 80586, 32 MB RAM, OS is Windows 98SE.

Second computer is 600 MHz Pentium3, 63 MB RAM, same OS from same CD.

What causes this problem?
