With recent versions of PotPlayer, a square white pop-up with a yellow PotPlayer logo periodically happens when launching a file:
I have a firewall blocking all PotPlayer traffic so I suspect this is a placeholder for an ad.
Older versions of PotPlayer do not do this.
I confirmed that PotPlayerPortable_1.7.21289.paf.exe has this issue.
Can the older PortableApps PotPlayerPortable builds be downloaded so I can test them?
I checked https://sourceforge.net/projects/portableapps/files/ but there is no PotPlayer entry with older versions.
