When displaying tables, the column names don't line up with the columns

q)show ([] index: til 10; id: 10#.Q.a; val: 10?1f)

-------------------
0     a  0.567081

and UTF8 text isn't being decoded the way it is for normal expression results

q)show "圣帕特里克节快乐"
STDOUT: "\345\234\243\345\270\225\347\211\271\351\207\214\345\205\213\350\212\202\345\277\253\344\271\220"

If I close my laptop for a few minutes then reopen it, I still have my connection to my Insights instance, and I can display expressions and see the results correctly, but show statements aren't working. It looks like it doesn't re-establish the websocket connection.
