this is old bug of flash
in flash8 it's not that present tho i guess I've seen it few times
anyways, simple touching that property before actual use helps. as simpel as
trace(txt._height) make textfield report correct value
2006/11/13, Muzak <[EMAIL PROTECTED]>:
Create a second textfield (hidden) that is as wide as the original, is
only one line high and does not autosize, dump the text in it
and grab its maxscroll value.
regards,
Muzak
