The Rich Text Edit fields are not displaying correctly in 2.0.x. The actual entry field is only a fraction of the panel where it is displayed (see attched screen shot). I first noticed this when editing an entry created with 1.7.4 however, when entering a new item the field is similarly sized.
Looks like your system is using a different editor. We at one point provided the option to select different rich text editors but ended up settling on one. I'll email you to set up a time to fix.
This has been fixed in 2.0.3 which will be available this week.
