Hi, I just upgraded to CorelDRAW 2018 from a very old version.
A basic question. I have a number of text objects over a page, and want to individually change their font size by clicking a new font size in the font size combo box. Each time I try and do this a pop-up appears titled "Change Document Defaults". I don't want to change the document defaults - just want to change the font size of one object and leave the default unmodified.
This is a product behavior change that I can't work out from the previous version I used.
What you describe does not sound like normal behavior for 2018.
If I have an Artistic text shape selected, then changing the font size in the combobox on the property bar simply changes the font size for that selected object.
What you describe is the behavior I expect if I change the font size in the combobox on the property bar when nothing is selected.
