Yeah, me too.  I can't even put any of the pastor's sermon notes on the screen because text editor is so buggy.  This is getting incredibly frustrating!!!! There have been three beta updates for this and it still does not work.

I have been trying to put the pastor's notes on the screen for the past hour now.  This is something the should take no longer than ten minutes.  

THe problem still exists with with build 5198.

Using build 5200 now.  Absolutely no difference.  In response to John's comments...

"The issue is only present when editing the text on a page (i.e. Page 1), but does not occur when "Cue" is selected in lieu of the Page." - That's the only way to edit individual lines of text.  Otherwise you have to make changes to the whole cue. 

"However, clicking on the page (i.e. Page 1) after the screen blanks out reveals the changes and allows for more changes." - Well yes, this is true.  It's the only way to continue editing.  This is where the frustration comes in.  If you're trying to format lyrics or other text in a special way (anything other than everything being the same font, size and color) you have to reclick on the individual page after every edit.  This is ridiculous and has been an issue since the earliest beta builds.  You have to understand that this makes creating a presentation an extremely long process and nothing short of infuriating.
