Some problems with some events of some components

[raulevm]

Thank you Alexandre.
I wanted to clarify that it is the OnAsyncClick event of the IWCheckBox that is executed twice.
Regarding problem 1 that I mention for the IWRadioButton: If I place two IWRadioButton (same group) and I click on the IWRadioButton2, the OnAsyncChange event of the IWRadioButton1 doesn't work, the same if I want to click on the IWRadioButton1, the OnAsyncChange event of the IWRadioButton2 doesn't work.
Regarding the problem 4 that I mention for IWRadioButton: The problem occurs when I want to insert code in the OnAsyncChange and OnClick events simultaneously. Thanks for your help
