Survey solution update

Hi. We are doing Household Budget Survey data collection using survey solution. In the beginning it was fine but once after update to version 19.04.5, the combo box get stuck. How to solve the issue

Dear SS Team,

I am experiencing the same thing with 19.04.04 where the screen freezed for a while and the Interviewers have to close the application and continue again.

Thanks in advance,

Best,
toga
