tab size in multilines

[Thomas Bock]

We convert tabs ($09$) to a number of spaces in textblocks comming from multilines with a height>1. Prior PxPlus 2019 the tab size has been 8 blanks. With PxPlus 2019 the tab size has changed to another amount of blanks(?). If I'm connected to a customer's server, then I have a tab size of 6. Some users of that customer have a tab size of 4 on the same server and in the same program. I cannot see any tab size property, so that must be a user setting.
Is there a way to set the tab size or can I query that value somewhere?

The TAB size spacing is controlled by the Windows control itself. 

Likely the difference is that for multi-lines we default to the newer Windows control which provides built in spell checking.  If you disable the spell checker the system should use the older control.
