Editor and Spellchecker error

All right; need some help or ETA of when this is going to be fixed.  When editing large posts and then running the Check Spelling routine, I get a solid colored background and just the Spellchecker pop up box; no post to see what is being edited or corrected. 

 

Also, the edit window has the most annoying tendency to want to center the body of text in the vertical direction instead of letting the cursor location be visible.

IE or FF makes no difference.  Both the same here.
