Thanks for the pointer. That works nicely with some filetypes, but it just stops my composition dead in its tracks when using PDFs. Is that a known limitation? How did people avoid this loading issue with QC2 other than your custom patch? Perhaps some sort of delay, or loading into an off-screen sprite?
