I have a PDF form created by a third-party. Every time I try adding my digital signature, the form turns black and illegible. Has anyone run in this? Any thoughts? I tried refilling the form and resigning, but it just happened a second time.
Repair was not an option. I found that rebooting my computer solved it, which tells me it most likely has something to do with my PC.
Have you tried to use Document/Repair PDF?
Perhaps try that after signing. Then try before re-doing the form if repairing after does not work.
Glad that restarting worked out. Those third party PDFs can be interesting to say the least.
