Ctrl/Shift-H works...only latest beta, version 1.1.9760.100
However, Ctrl/Shift-L doesn't...a box opens up with this text: "Performance Logging Started"...
Not here, as I don't trade any options, as I assume it is, weekly options, expiring next Friday Sep 10th?!
At least make it user selectable, so I don't have to see it if I don't want it. Thanks.
Black theme here...
The way I get around it...
Click chart, hit F11 (or show ribbon)...Main/New Chart/Same as this chart. Delete the one with the white border, replace.
Maybe not a perfect solution, though it works for me.
