I recently updated Windows to the current set of updates after the security alert went out, and something has broken Propeller Tool. I reinstalled it to see if that would fix it, but no luck.
What I see is in the attached picture. The black vertical bar is blinking, it seems to be the cursor. If I scroll my mouse wheel, the scroll bar on the right moves up and down as expected, and the black bar gets wider. But no text appears on screen. Picking the Condensed, Summary, or Documentation buttons gets different versions of the same thing.
I was able to get the current version of Propeller IDE from GitHub, so I can continue to edit Spin, but I hope someone can figure out why this is going on.
Windows 10 Home, 64-bit
