A month or so ago, PDFs opened by double clicking started to take ~15 seconds to open. However, if I drag and drop the file onto Bluebeam, or do file->open, or use the Bluebeam history, the file opens nearly instantly.
It doesn't matter if Bluebeam is already running or not. The file size and content does not seem to have a significant effect. It also doesn't matter if the file is local or on a network. Files open quickly in Adobe and other viewers.
I'm using Revu x64 CAD version 20.2.85 and running Windows 10 Pro.
Any ideas?
