I've already used the EnhancedList, and TextEdit from the SF DevEx wrapper and it works ok. I'd rather you checked with your developers for this, as the goal for our evaluation of the trial for us is to see if it will work seamlessly with our existing investment in DevExpress.

Could you post an example app that works with the EnhancedList and TextEdit but not with the Maintenance form?  Likely there is just a messed up reference somewhere, which is easy to fix once found....but hard to find without a project to look at.   That way not only can the developers take  look, but there are other users who use DevX and they can test it as well.
