Perhaps it is a bug - it could occur if the message handler for the
control was not setting the result of the message to 1. Then again, that
might be a feature!
To fix it, you could use a flag that was set when the OnKeyDown event
fired, and reset it when the OnKeyUp event fired. Otherwise you may have
to trap the message on the popup form and swallow it by setting it's result.

Hi Phil
You are right ! We do use the OnKeyUp event. I have just built a
test app with our component and a plain TEdit control and both
components get the Enter in their OnKeyUp event if they were the
active component before the other screen was opened !!!
We are using D6 could this be a bug?
More importantly, assuming we need to use the KeyUp event, does anyone
have any ideas how to get around it?

Is your customised component responding to the OnKeyUp to check for
the Enter key? If this is the case then perhaps the key-up message is
being transmitted to your component since the other screen is now
closed - although I would have thought that could only happen if the
other window was responding immediately to an OnKeyDown as opposed to
a KeyPress event. Could be worth checking.

Hi All
We have a customised component that pops open when the enter key is
pressed. However sometimes when an Enter key is pressed in another
screen (open over the screen with our component) and the Enter key
is pressed on a close button, the Enter key seems to travel into our
component (which has focus after the other screen is closed) and pop
it open. This is undesirable :)
Any suggestions?
