Fairly regularly the IDE gets into a state for me where vertical scrolling for the form does not work. The form is tall enough to require vertical scrolling to see the rest of it in the IDE, but the scrollbar isn’t there and using the mouse wheel doesn’t scroll.
I can generally get the scrollbar back by switching to split screen and back, or sometimes to the code tab and back.
I haven’t identified a way of reproducing this, but it’s happening often enough that it should be showing up for other people if it isn’t just something specific to my browser(I’m on Chrome).
I don’t remember this happening before a few days ago, but maybe I just hadn’t tickled the right conditions before then.
