[Epidata-list] Problem with division by zero

Hello! I have a problem with all known example "first", and BMI calculation. When I left blank field in "high" the warning "division by zero" is shown. The "ignoremissing" command is not included.

The second question is why EpiData writes in check file command "missingvalue all [same name of labelblock]". It happens when I'm working "manually" with check and then I open check editor.

My build is: 040903
