Portal doesn't scroll
I'm modifying the inventory starter solution, as part of that, I've added a vendor table and a vendor number table. The inventory table relates to the vendor number table which relates to the vendor table. So one item may have several different vendor numbers from different vendors. All that works well, but I've added a portal that shows the name (vendor table) and number (vendor number table). The portal is 2 rows with scroll bar, however if I have an item with more then two vendor numbers, clicking the scroll bar makes the screen go funky. I've attached a screen shot of the weirdness, the fields become clickable and are blank, also the alternating background color of the portal disappears.
