--- Comment #1 from Terri Brooks <tb...@progressive.com> ---
I was able to replicate this issue using OpenOffice version 4.1.1 and with the
newer version 4.1.2.  I tested this on Windows 7 & Windows 10. (Note: I did
make an additional observation which I documented following step 10 below)

Steps to Recreate: 

Test 1:  Font Point Size 6

1. Open an existing presentation or create a new blank one in Impress.
2. Verify that the ‘Text formatting toolbar’ is visible in the ribbon area.  If
not, then go to menu:   View > Toolbars > Text formatting to open the toolbar.
3. Add a new slide to the presentation. 
4. On the new slide add a line of text (any text).
5. Select the text and set the font size to 6 points.
6. With line still selected click the ‘Reduce Font’ button (in Text formatting
toolbar) twice and note the font size is reduced to 5.4, then 4.9.
7. click the ‘Increase Font’ button (in Text Formatting toolbar) one time. 
Expected Results:  Font will decrease to font size 5.4
Actual Results:  Font size automatically increases to 6 points.

Test 2:  Font Point Size 9

8. With the line of text still selected - set the font size to 96.
9. Click the ‘Increase Font’ button (in Text formatting toolbar) twice and note
the font size is incremented twice:  My system increments:  105.5 > 116.1 
10. With text still selected - click the ‘Decrease Font’ button twice in order
to return to the original point size 96.
Expected Results:  Font size will return to ‘96’
Actual Results:  The font size decreases to ‘94’ and does not return to the
original 96 points.  On my system it decreases from 116.1 to 104.5, then
finally to 94 points.  (similar to Richard’s results)

Additional observation:  In running some follow up tests I noticed at the end
of step 10 IF I click to decrease the font size until I reach size ‘88’  – and
then click to increase the font – I am returned to the original font size of
‘96’.  It seems to revert back to the standard font sizes once you hit font
size 88.  

Additional Comments regarding above tests:   
- For step 6:  It’s not necessary to just click ‘two’ times - you can
increase/decrease the font all the way down to the smallest size of ‘2’ and get
the same results:  Once you click ‘Increase Font’ – it will automatically
revert right back to point size of ‘6’.

-For step 10:  It’s not necessary to just click ‘two’ times - you can increase
the point size all the way to the maximum size of ‘999.9’ with the same results
– you are never able to get back to the original point size of 96 until you
reach size of 88.

-I wanted to note also that I ran the following variations when executing steps
1-10 above – and none of these variables made any difference to the test
results.  All tests yielded the same results as described above:  
•    Various font types/styles
•    Variable text in text line (numbers versus letters, all caps, all lower
case, mixed case, etc.)

I've attached the Impress document that I used in order to perform testing 


Tested on the following Systems:

System 1:
Windows 7 Ultimate 64-bit version 6.1.7601
AMI Alaska - 1072009 08/13/13
Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz Intel64 Family 6 Model 58 Stepping 9

System 2:
Windows 10 Pro
ASUS All-in-one PC
Intel® Core™ i5-4200U CPU @ 1.60 GHz 2.60 GHz
