When I open an attached PDF in the X9 reference window, it exhibits odd behavior when navigating from one page to the next. It immediately jumps to the page following the one I’m interested in reading. It refuses to display the first page of any PDF, whether I use the scroll button, arrow keys, or click on the page. When I click on any subsequent page, it immediately jumps to the next page following the one I clicked on.
The only solution I’ve found is to open the PDF in an external program, such as Preview or Adobe Reader in Mac OS. However, I’d prefer not to have to choose between many open Preview windows to read the PDF, and I’m hoping I can get the reference window to work in X9. I’m using X9 on the High-Sierra Mac OS (10.13.6). Memory use is moderate (14 of 16 GB).
Once, the problem seemed to go away when I changed the arrangement of the reference pane from “Right-split” to “Right-PDF”, but then the problem returned. It also seemed to resolve after I closed and reopened X9, but it now persists after reopening X9. This seems to be a bug in X9, but I’m a new user and haven’t used earlier versions of EN.
