I had some confusion in the previous report, but I can explain the problem more clearly.
In My Journal Database, the default margin of the paragraph and table in the RichText field is 1.0 inch right from the ruler origin. The left side of the client window ( visible box inside of the notes framework ) is 0.75 inch right from the ruler origin.
Create a new table, and the table left side is set 0.25 inch right from the client window left side and the margin size is 1.0 inch.
Move the horizontal scroll button 0.75 inch left ( which is at the left terminal in the scroll bar ), and the table left side is 1.0 inch right from the client window left side and the margin size is 1.0 inch.
Change the table width option from ‘Set to Margin’ to ‘Set with Window’, and the table left side is set at the client window left side and at the ruler origin and the margin size is 0.0 inch.
Return the table width option to ‘Set to Margin’, and the table left side is set 0.25 inch right from the client window left side and the margin size dose not return 1.0 inch.
WEIRD!! It is 0.25 inch that the margin size is set.
