Here's a video on the bug
https://www.youtube.com/watch?v=N3SvbHwz6_8 (Sorry if I'm not allowed to post youtube links) So I tested this out on another PC and I can scroll the in-game server browser without the webpage scrolling. Could it be because I have installed a new GPU? (I installed it 2 weeks ago I think) GTX 1060 OC, and I installed the new drivers and uninstalled the old drivers from my other card (GT 630). I uninstalled flash player using the official uninstaller program and reinstalled it, cleared cookies multiple times, reinstalled chrome. still keeps doing it. I also resetted chrome in the advanced settings and chrome:flags too. maybe there's something in the chrome folder or gpedit.msc? Also like I said earlier since this didn't happen on my mom's PC that I tried it out on, I don't think anyone else is experiencing this, so taking that in mind this seems to be a browser/PC specific problem, I also tested it out with other flash games on coolbuddy.com and It didn't scroll, what's going on? :/
There's a demonstartion in that youtube link of what's going on. Also a minor secondary problem that I need help with (even though my ping is so low!) near the end of the video, thanks guys
