I'm calling a custom page from the Sales Quote subform using Page.RUNMODAL in NAV 2013R2 with Cum. Update 19 on platform and application. Users are working on client workstations using a VPN connection to the NAV Service. Users are getting frequent instances(daily) where the page focus is moving back to the Sales Quote page rather than staying in the modal page. This behavior is not readily duplicated. Users can get out of the modal page and repeat the same steps without producing the modal problem.
