[DUG]: RadioButton requires 2 clicks

[Steve Galyer]

I posted this problem yesterday but got no response so I have attempted to explain it better.   I have a D6 application.   When I move out of a TEdit by clicking on a TRadioButton or TCheckBox, the OnExit code for the TEdit executes and the focus moves to the TRadioButton or TCheckBox but the OnClick event for the TRadioButton or TCheckBox does not execute - the button initially appears grayed, but reverts to the normal colour and remains unchecked as soon as the mouse is moved. To make the TRadioButton or TCheckBox checked you need to click it a second time - even if you want to close the form you need to click the close button twice.   The problem only arises when the OnExit event from the TEdit displays a MessageDlg - there is no problem if the MessageDlg does not get displayed, so I suspect the problem lies with MessageDlg.   I have tried putting Application.ProcessMessages and forcing a click using SendMessage in various places without success.   Anyone got any ideas on how to fix this problem?   Regards Steve Galyer
