Say, 5 is stored in memory 0, with a clear stack:

5 * 5: RCL 0 Enter x => 25 -- so far so good
5 * 4: RCL 0 Enter 1 - x => 100 -- ???

This behaviour is completely logical and the way all RPN HPs are supposed to work.

Your first example:

Code:

T    0     0     0
Z    0     0     0
Y    0     5     0
X    5     5    25

   RCL 0  ENTER  x

Continue with the second one:

Code:

T    0     0     0     0    0
Z    0    25    25     0    0
Y   25     5     5    25    0
X    5     5     1     4  100

   RCL 0  ENTER  1     -    x

You see that the "1" overwrites X because ENTER disables the stack lift.
Add a second ENTER and it will work as you have intended.

On the other hand in the first example ENTER is directly followed by the multiplication, so X and Y are multiplied and you get x².

I think it is fine this way.
