Bug in how text is rendered in textBox JMP16?

We have updated to JMP 16 and immediately users pointed out some bugs in the output of our scripts.

For instance, consider the script below:

detailsText =
"This is long text that is made dynamically\!nit has some dynamica numeric values\!n"
||"each on of which is important and  \!nneeds to be shown formatted in <b><font color='Red'>RED FONT</font></b>"
|| " which might also by dynamic\!nLike this: <b><font color='" || "Red"
 || "'>" || Char( 6 ) || "</font></b>\!n this here is your value and " || "here is" || " another value: <font color='green'>" || Char( 0 ) || "</font>"
 ;
	
detailsTB = Text Box( detailsText );
	
	//detailsTB << Set Font( "Agency FB", 12 );
detailsTB << Set Font( "Calibri", 12 );
detailsTB << Markup;
detailsTB << Justify Text( "right" );
	
w = New Window( "Formatted Text", detailsTB );
	
//detailsTB << Set Font( "Agency FB", 12 );

it will result in the window shown below.

But if we uncomment the line that sets a different font (in this case Agency FB), or run this command afterwards, then the text (even though is still present in the textbox, is not rendered like below:

And I'm sure the text is still there: it's just not rendered.

How do I fix it? If this is a bug - is it known? When will it be fixed?

My guess is that the height of text box changes for some reason and last line will be outside of it (as in hidden). There are most likely better ways to handle this changed behaviour but... quick fix could be to use Set N Lines

detailsTB << SetNLines(10)

In my experience JMP does not handle fonts properly -- specifically the height of various fonts can be off a bit. My only solution has been to find fonts that don't give issues and avoid fonts that do give issues (most fonts seem to give issues)

Thank you for the report and example - this has been reported and will be fixed in a future release. The issue appears to be related to line heights - in addition to the suggestion from @jthi you could add a "\!n " on the end to add more vertical space, or break the string up into multiple text boxes.

Thanks a lot! Simple adding

"\!n"

did not help - bug's behavior is pretty elaborated and it's hard to pinpoint when it will and will not show last line/several lines. But setting number of lines as you mentioned definitely helped.
