Just to be sure. Did you press 'Enter' after typing a number?
Viewing post in Size not doing anything?
I seem to be having issues as well and I am hitting enter. sometimes it works, sometimes not. It seems to depend on the number. Most 3 digit numbers (or less) seem to work but yet some do not. Then I thought maybe it was a percentage but I'm able to go above 100 and get a result. But to try to get a town of, say, 3,000 just doesn't seem to work.
