I am facing an issue whereby Webi doesn't display all the available objects and I can't scroll down in the Result Query Panel as per attached screenshot. Please help on this, thanks!
Looks like you're using Freehand SQL, which is a fairly new feature and not fully baked yet.
I tried it out (SP06 Patch 5), and had the same result. However, when I dragged the right-hand border out a bit, the vertical scrollbar magically appeared and I was then able to scroll down. Not sure if that'll work for you.
