Not only do TrackInfo Plugins operate in Read Only Mode what you see on the screen is the results of HTML formatting instructions. Therefore if you make any alterations to anything displayed in a TrackInfo Plugin window, like modifying/correcting some lyrics, those changes will not happen in MC.
When it comes to properly formatted lyrics, like the ones in HPBME's posting if you select those lyrics from a TrackInfo window and paste them into the MC lyrics tag you will end up with a set of lyrics that has no empty/blank lines in it. That's why my TrackInfo Plugins do not allow anyone to select anything that is displayed in it's windows.
As for that "whole slew of TI's" all except 1 of them ship with MC34, the only 1 that is missing is MCC Ultra, the Classic Music Friendly version of MC Ultra.
If you click on the link in my forum signature you can read about my TrackInfo Plugins and if you are a Classical Music fan download MCC Ultra; which like MC Ultra uses Actual Intelligence to make the other members of the MC Ultra family of TI's theoretically redundant/obsolete.
