>Dmitry--I wanted to let you know that I think I've solved my problem. In my case, the textbox in every column in the grid that isn't supposed to accept focus has RETURN .F. in its When method. When I turned on the Event Tracker, I found that ultimately the Valid of the textbox in the column that accepts focus was running and it apparently was calling some code that messed with the cursor under the grid. I wrapped that Valid method so that it wouldn't run in View mode (this app requires users to explicitly put forms into Edit mode), and that appears to have solved this one. Haven't turned it over to the client yet for them to pound on it, but so far, so good.

Glad to hear you got to the root of the issue.
Is it true that When and Valid aren't Windows events per se, more like something left over from FoxPro DOS ?
