This is not solution for your problem (i'm not a draw guru), but you should rather use
'compose instead of 'reduce:
compose [
fill-pen blue
box (emp1) (emp2) white
text (emp2) "text"
text (emp2) font-size 5 "text"
]
It's a little bit faster bacause it evaluates only parens...
>> t1: now/time/precise loop 5000000 [reduce ['number random 100]] t2: now/time/precise
t2 - t1
== 0:00:12.959
>> t1: now/time/precise loop 5000000 [compose [number (random 100)]] t2: now/time/precise
t2 - t1
== 0:00:12.067
