Hi K D J and welcome to our community
Are you seeing the broken lines immediately after recording
or are they only appearing AFTER you rescale your project? If you
are only seeing them occur after you change the size of the
project, it's probably the resizing that is nailing you. Not sure
of any way around that other than to ask if it's possible to resize
what you are recording so that resizing isn't needed. I'm guessing
that may not be the case.
As for adjusting the captions, all Captivate will do is to
adjust the size of them. It does not alter the font at all. Some
folks expect that if you take a Caption with a 16 point font and
scale the project smaller, the font may change from perhaps 16
points to 12 points as a result. Nope, doesn't work that way. Only
the dimensions of the caption will change. Additionally, there is a
limit to how small any given caption may be. This is determined by
the bitmap image used for the caption background.
Cheers... Rick
