I have no idea where that message is coming from, but it is not in the framework ?!?! It sounds like you have a BrowseInfoPanel attached to a browse and may have something in the RowChanged event. I believe that this is going to have to be in your code as this is not a function of the framework. You might look around and do a search on this text.
Hey Fabian.
They are making you work withouth breathing?
And you have accomplished that?
Anyway, when you search in VS, have you noticed the "Look in:" and "Find options" in the "Find and Replace" dialog? That might be the reason why you haven't found your message. Just a guess, sorry if you were aware of this already.
Abraços.
