Not caused by Win\blinds but ? I noticed
After the last Win 10 update I noticed Steam is not working correctly things like the Stores page gone but looking in taskbar opened, same with game Library, would work ok in small mode for short time but stopped, worked fine in Big Picture mode. Sorry I'll cut it short I closed Win\blinds and Steam worked fine I found that after a while installing and reinstalling Steam a few times, but everything work well together before last Win 10 update. My other PC Steam worked well again until the dreaded Win 10 update, just seems so weird as EA Origin and GOG Galaxy work fine, just something between Steam, WindowBlinds and Win 10 update. Any pointers or advice would be appreciated.
