First Scenario Screenshots

Software and hardware configuration used:
- Operating System: Windows 10 Home, 64-bit;
- Processor: Intel Core i5, 1.7GHz;
- RAM Memory: 4Gb;
- Open Office 4.1.3.

First scenario
--------------

Steps:
1. Open OpenOffice Writer;
2. Set the measurement unit to 'cm': Tools menu | Options...| OpenOffice Writer
| General | Choose as Measurement Unit 'Centimeters';
3. Create a new document: Menu File | New | Text Document; 
4. Set the Paper Format to A4: Format Menu | Page...| Page tab | Select from
Format drop-down list;
4. go to Header Tab;
5. Enable Header;
6. Set Header Height to 29.7 cm;
7. Change focus from Hearder Height;
[header height = 20.06 cm]
8. Repeat steps 6 and 7;
[header height = 20.56 cm]

Expected output:
- header height should be set to the same value after steps 7 and 8;

Actual output:
- header height was set to different values after step 7 and step 8.

This shows an inconsistency in handling the same boundary value. For A4 paper
format, 29.7 cm is the paper height. I have enclosed screenshots for this
scenario.


Second scenario
---------------

Steps:
1. Open OpenOffice Writer;
2. Set the measurement unit to 'cm';
3. Create a new document;
4. keep the default Paper Format to Letter;
4. go to Header Tab;
5. Enable Header;
6. Set Header Height to 27.94 cm;
7. Change focus from Hearder Height;
[header height = 18.65 cm]
8. Repeat steps 6 and 7;
[header height = 19.15 cm]
9. go to Page tab again;
10. Set the Paper Format to A4;
11. go to Header Tab;
12. Set Header's Height to 29.7 cm;
13. Change focus from Hearder Height;
[header height = 20.56 cm]
14. Repeat steps 12 and 13;
[header height = 20.56 cm]


Expected output:
- header height should be set to the same value after steps 7 and 8 for Letter
paper format;
- header height should be set to the same value after steps 12 and 13 for A4
paper format;

Actual output:
- header height was set to different values after steps 7 and 8 (first paper
format); the header was not enabled before;
- header height was set to the same value after steps 12 and 13 (second paper
format); the header was enabled before for the Letter paper format.


This shows an inconsistency in handling the same boundary value. For Letter
paper format, 27.94 cm is the paper height.


Final considerations
--------------------

1. the first scenario indicates there is an inconsistency in handling boundary
values when setting the header height;
2. the second scenario shows that this happens always to the first paper format
used; it doesn't matter the user selects a new one from the list or not;
3. this issue is related to the first time the header gets enabled, no matter
what paper format is used:
 - 1st time: if header is enabled and footer isn't enabled, the program
considers the footer height = 0.50 cm;
 - 2nd time: if the footer isn't enabled, the program considers the footer
height = 0.00 cm.
