Recently I noticed two issues:
- Searching for some reason sometimes doesn't start from the page I view. Not sure what context causes this. I typically notice that the document is navigated backwards even though I'm sure there are results after the current page. And sure enough, repeating the search will take me to the appropriate result after the page I'm viewing.
- I think this might be related to the issue that I had on Windows 8 (now I'm on 10). When I go to full screen a second blank taskbar button appears, which prevents me from conveniently alt+tab-ing to and from pdf-XE. It's rather annoying and pointless.
