When Im adding text and justifying it, there is irregular space between words.Any suggestion, what am I doing wrong?
Font used: Arial 14px
Webbuilder 15.3 32bit
See the screenshot

Yes because you are justify both left and right side. The first and last word of the line fully justify and the inside words space evenly. This is inherent in full justify.Even broadening the column has no effect, some where else the gap increases.
Even trying "Wrap Text" extension has no effect, irregular gaps remain
