The stupid "dark overlay" won't go away on the screen!

I just created a forum account but the dark overlay with the "Your first notification! Select it to begin." saying comes back once I click on the actual screen (as in I am typing this with the dark overly now). This is frustrating as I need to ask an actual question about your product but this doesn't make me feel very confident in them. :confused:

Hi @tyelrod

Thanks for your feedback.
No need to worry, the forums software isn't actually developed by pdfforge but it's a (very good) third-party software.
We didn't hear of this issue before.
Did you already try another browser (Chrome/Firefox) or cleaning your internet data (or incognito mode)?

Logging in and out gets rid of the problem. It is admittedly very annoying though.
