i should probably mention that the same object is used for several
instances but it's just the one that doesn't use the elCreditFormat
TextFormat that fails to scroll
thanks

i really hope someone can help me here
i have a textfield that is set up with a defaultTextFormat and has
several setTextFormats applied to type within it but when i try to
overflow it and add a scrollbar, i get no scroll result.
I've looked into it and it seems that no matter how much type goes
in (either more or less), it shows that there are 4 lines (using
TextField.numLines) in it.
i've included the method below and commented where the issue is -
note that there is a textformat that is applied if the elCredit
property is set that is the thing that seems to be the problem:
when it is added, the numLines traces to the actual number of lines
(and the scrollbar works) but when it doesn't get used, numLines is
4 regardless of content and the scrollbar doesn't work
please help as i'm really stumped on this issue
thankyou
