I tried it in PE 3.11.0, same issue.  Narrowed it down to line 27:

do: loop until screenexists = true

For some reason this causes the program to hang only in PE.  I've commented out this line in the code up top, should work for you now.

Odd, this code is functionally what the PE wiki recommends.  Seems like either a PE bug, or an obsolete wiki article:

Yep, I've run into that too. Use

_DELAY .25

instead if a pause is needed for anything to "catch up".
