So previously you could use find (Ctrl + F) to locate text and it would zoom to the position of the text with no problem. For some time this function seems to have stopped working. Dispite there being several occurances of the text, the program does not zoom to the first instance and then the next as it did in the past. It now zooms what appears to be randomly around the document. Using advanced find will list all the occurances correctly but clicking on them does not zoom to the relevant occurance.
I have unchecked the fast find function but this makes no difference. The documents are PDFs of drawings. The function has always worked in the past (probably more than a couple of updates ago).
