This slow scrollbar behavior is limited to TfrmAllCompilerOptions. All other screens are fine. Made a small program with a TScrollbox, and it doesn't have that behavior. I see an OnIdle handler that seems to do quite a lot (RenderAndFilterOptions). Wouldn't that intervene with the smooth tracking of the scrollbar?
