My "fix" for server list not showing servers

I've been having issues with the server list not showing all of the servers, and it takes several minutes to show the few servers that it does. I looked around for the Steam_AppID.txt file suggested by Yoshiro (I'm not entirely sure it's related to my issue, but whatever), but it's not in my C:\Program Files (x86)\Steam\SteamApps\common\KillingFloor folder.



Instead, what I found "fixes" this issue is to alt+tab. When the KF window is maximized again, all of the servers show up in a timely fashion (you may need to alt+tab multiple times). Glhf!
