* One behavior that goes at least to 6.35, in handling blank raw at the bottom.
* Starting in 7.66 I see a behavior where the visible rows change from <enter>
* Another is position of Ctrl+F window uses old editor location, starts somewhere around 7.3
Quirk#1:
Step 1: scroll to bottom of Script Editor, press <enter> insert new line below bottom line
Step 2: use mouse to scrollbar up to middle of the script, then scrollbar back to the bottom
Result: doesn't let you see the blank row at bottom unless you <down arrow>
I guess this has something to do with the behavior of <ok> pruning blank rows from bottom of scripts.
Quirk#2: window jump-shift, this one is less harmless
Step1: open Script Editor
Step2: page down a couple times, then arrow down until the top line coincides with top visible line in editor, and is a script line that doesn't go past the right edge of window
Step3: arrow or click to tail end of that top line and press <enter>
result: if former lines visible were lines 331-350, pressing <enter> on that line changes visible range to lines 330-349, making the previous line visible and the inserted blank line is the 3rd line instead of the 2nd.
Quirk#3: Find window remembers wrong position
Step1: Open Script Editor
Step2: Open Ctrl+F find window, then close it
Step3: drag Script Editor to new location
Step4: Open Ctrl+F find window again, and it stays in the old location, unlike Ctrl+G that dutifully follows the editor. Rumor has it that this is more extreme on dual monitor which i don't have.
