Hello Christof:

Less the term "dangling" (I had to look for it in an on line English-Spanish dictionary) I think I understand what you say.

When I shut down the system (typically when I'm debuging) the "object OENTORNO is not found" appears.

But that's not the case of my clients.

I'll tell you the last case (not the only one)

A grid

First column, textbox is the current control

Valid event of textbox executes one and many times

Suddenly the valid event attemps once more select the cursor but the cursor now is closed...

And so...

While I'm writing to you I think... You mean the user press any key that provokes shut down... I can't beleive that in every case. If I ask them about that they always would reply "Not. I didn't do anything but what you indicated..."

Well. I thank you very much.

Héctor
