<br> tag confusion -- is this a bug?

I have 2 txt fields on two frames, respectively. I double space lines on txt that gets loaded dynamically by using "

". So, when the playhead arrives at either frame, the text gets set to html = true, and then the text gets loaded. I load txt into the field on frame 1. looks good. Load text into the fiedl on frame 2. different text, looks good. I return to the frame 1 to load the same text that had previously occupied it, after emptying it out first of coarse. However, it seems that everywhere i used
, another
is added?! …so "
" becomes "

"… and "

" becomes "

" what is this craziness? I fixed it by doing this: first line: "text text text
" next line (space): "
" next line: "text text text
" reloading that doesn’t produce mysterious extra linebreaks…
