This isn't something that was done intentionally. I have added the line of code so that pressing the Enter key now opens the current field for editing, in both the data sheet and form. As Dave mentioned, the tab key already did that, and pressing any character also opened the editor and inserted that character.
I would expect that, and that is what it does in my tests. I tried it with both standard Text Editor objects and when using the pop-up editing option. If you can come up with a sequence where that doesn't happen, please let me know.
Sorry, I don't recall that. Could you either find the old thread and bring it to my attention, or open a new thread here with details about what you are talking about? The only way I know of to have a non-empty cell look empty is if the cell has multiple lines, but the first line is blank. Panorama 6 was the same way.
