First off, I like the work. As for the problem itself, I'm not too sure on how to fix it, I mainly use paint.net, don't know much about SAI. :\ I'm no help. :T

thanks, and it's ok

What version of Windows is it?

windows 10

You might be able to help with this problem:

I'm not sure I'm the only one experiencing this exact problem, but yesterday I encountered a mysterious pop-up box appear at the top of the screen (near to the YouTube panel but offset to almost the middle of the screen)for a fraction of a second before it disappears again (for the record, I'm using a Lenovo All-In-One desktop with Windows 10 as the Operating System) I was wondering whether you experience/have experienced that same issue. (It's still ongoing as of today)

hmmm, can't say I have

Nevermind, at least your problem is fixed
