@John_Brock@JohnM - note that this does not appear to be entirely fixed, I just had it happen in my current 7.2 RC (7.2.20343.11011, 08-Dec-20) - I am trying to figure out a way to reproduce it consistently - in this case there was no pasting of anything into the notes panel, but at some point all the Notes panel input went to the command line again. I fixed it by switching tabs to something else and then back to notes. Will try to create a ‘recipe’. There is also this post that just appeared, but they may be on 7.1.
Edit - it turned out to be surprisingly easy to reproduce… so either it isn’t fixed yet in the version I have, or it somehow got ‘unfixed’. (7.2.20343.11011, 08-Dec-20)
In my case Layers, Notes, and MacroEditor are panels docked together on the right hand edge. (i.e. as separate tabs)
Launch Rhino with a new blank default template (with Layers as the active tab)
Click on the Notes tab to make it active
Type the following on one line in Notes: This is a test (Do not press Enter, leave the cursor at the end of the line.)
Go back to the Rhino window and choose a tool, say Rectangle - make the rectangle.
Go back to the Notes panel and click to place the cursor at the end of the test line. (note the cursor is flashing in the Notes panel, indicating it is active)
Hit Enter as if you want to start a new line in Notes.
