Pixel space coords starts with 0, 0 to 1023 is equivalent to 1 to 1024, that blue line is just the data window padding, you can ignore that.

I never get these kinds of errors on windows, you report a bug, or email the support for this.
However, "Richer Errors" here means that if you do the thing specefied you will get more detailed error desicription, to know what's going wrong.

You can do this is using the "pane" command in hscript,
you can write-
where -f means open a floating window, and with -m you have to specify the pane type, for spreadsheet it is "details", you can create shortcuts for other panes using this command too.
Assign this command to a shelf tool, and create a shortcut for that, and there are more options for this command you can check too!
