It is a mouse and shift key combination. Sometimes Windows 98/ME will forget to
clear the shift state (or it may set it due to some transient instability during
some program exit). The shift combined with a click on an icon marks the range
of icons as a set (like in cut & paste operation), beginning with the one which
was highlighted before and the one which is getting a click now.

One more thing has to happen to get the primary problem. For example if your
mouse has a bounce problem (i.e. occasionally it generates multiple fast clicks
instead of a single click, depending on which point of the button area your
finger presses), then Windows will see this as a double click and perform the
double click operation on the entire marked set. Even if you have a good mouse
and perform double click intentionally, the stuck shift state will also cause
the double click execution on a set. Or if you have the shell set-up to use
single click to simulate double click, again you will get the problem.

One thing that fixes the problem (if you don't mind extra steps) is to toggle
shift key down & up after applications exit. Or click a mouse on an empty area
of a desktop. If the source is a mouse bounce (and you will know it because it
will show occasional spurious double clicks unrelated to the shift problem), you
could replace mouse.

We all need to tip our hats to Bill Gates' business genius, since only a
business genius could dominate the OS market with Windows.
