Payslip / Salary Statement - Scrollbar problem

Hello,

We are using ESS WDA with the included service for displaying the salary statements in PDF format.

When we select a salary statement in the "Overview and Selection" table, the correct PDF is displayed in the browser.

If we use the scrollbar at the table, and scroll down the list, the one entry, which is selected, will be refreshed by each click on the scrollbar.

By refreshed I mean it reloads the PDF in the window.

Can we somehow prevent the program from reloading the selected entry PDF? Or can we say that by clicking on the scrollbar the previous/next entry should be selected? Because I found nothing in the properties.
