Not agreed Patrick. We are talking here about the Viewer.
I suppose you checked within the Editor. When myself, I look there, it shows indeed like in your print screens.
Is that possible?
Please see the attached PDF (screenshots from the Viewer).
I just saw that I made the test with an older version of the Viewer (2.5.319.0), but the newest version I could download and install (MSI Network installer 32 bit - strangely 2.5.322.4 and not 2.5.322.5) still shows the hyperlinks in the same manner.
Still not convinced, I downloaded and installed via the EXE installer (32/64 bit), and so I had finally version 2.5.322.5, but the problem with the 'thick' lines remains.
So, I believe the solution for xuanliu is just simple: press CTRL + 5 and switch to 'thin' lines.
We might still encourage xuanliu to try the switch from PDF-XChange Viewer to PDF-XChange Editor V6,
that can be downloaded via the following link:https://www.tracker-software.com/produc ... nge-editor
