Judah....
Our classroom is getting the same behavior, the "OK" button is greyed out, but we are fortunately able to just plow ahead and press ENTER on the keyboard to get the action to complete.
Weirder for us is the missing event timeline/history/"play" list that used to be at the bottom of the screen. Now we have to undo multiple times to make parametric-like changes to previous fillet radii etc...
We also lost number pad entry on ALL floating dimensions, only the main tool window box allows dimension entry, ....the little "on-site" box that floats near where the mouse pointer is has become completely unresponsive to any number pad entry from any part of the keyboard, the numberpad, or the top row.
Crashes seem more frequent too, wish we could go back to the previous version, but still committed to making this work as our school's CAD recomendation.
It's just hard when I come in and spend 30 minutes of class looking foolish trying to get things working, the kids just give up and many have already decided the E for Engineering in our STEM classes is just not something they can "do".
It's frustrating.
I tried to post a vid of these changes, but I'll show a pic or two instead....
Notice the blue highlight on the floating box, but no keboard entry will be accepted there.
Notice the OK button greyed out once the number is entered ....and yet the preview has no signs of error warning, and in fact completes just fine if the Enter button is pressed on the keyboard
Notice also that the history is now vertical and the horizontal icon bar of past actions is gone.
