Attempting to scale a file 130%. After grouping all objects and using either Selection Tool+Ctrl+Shift or the Scale tool results in different line breaks than the original. It seems to oocur primarly near objects with text wraps but sometimes not. I also noted that one word in the middle of a paragraph didn't chnage size or leading accordingly.
This is ID CS4 6.0.6 on a PC.
Scaling text can can behave strangely if the font ony uses kerning pairs above a certain size, and your metion of the text wrap is another clue. The size of the wrap doesn't change with the scaling.
Not sure why some text wouldn't scale. Could be an applied style...
