As you should be.  That is how WinExec() works - it creates a new
process each time it is called.

You can't.  Notepad is not designed for that, and there is nothing
WinExec() (or CreateProcess(), for that matter) can do about it.

The called program, not the calling program, controls how the file is
loaded.  If the called program does not want to run multiple
instances, then it has to control that on its own.  The calling
program has no say in that matter.

Then I suggest you not use Notepad at all.  Display the log in your
own UI, such as in a TMemo or TRichEdit control..  Then you have full
control over it.  If you must use an external program, then write your
own.  Then it can avoid multiple instances of itself.  It is a very
common feature to implement, so there are plenty of examples floating
around to look at.
