Aldeed:tabular "processing..." question

Hi I’m using aldeed:tabular to show a list of users.
There are 9 users and it displays them fine.

Oddly if I choose 25, 50 or 100 from the show entries drop-down.
The “processing…” message appears and doesnt remove itself

When I choose the 10 from the show entries drop-down it goes away.
Is this an expected behavior?
