TIWHTMLCheckBox click

Our users are accidentally hitting the space bar when they are on a TIWHTMLCheckBox and the checkbox is checked (which they are not intending to). Is there a way to turn this off. 

User should be only able to check the checkbox with the enter key or by clicking the checkbox.


Please note that it is standard HTML checkbox behaviour to be able to check it with the space bar.
Unfortunately it's currently not supported to disable this behaviour.
