o.k. i do a lot of translation work: and split the scree. The top is the original (more often than not a PDF ... however a small one of 10 pages max) and the bottom is the working translation ... If I switch to the top (the PDF) and e.g. copy a word that I want to include in the translation, and then click on the bottom scrivener seems to hang: I get colourful ball that spins and spins ... and then it stops and I can start writing. Given that I do this regularly as I work this is very annoying and takes up a great deal of time.
The problem is not the PDF problem ... i have made the PDFs short ... any suggestions?
