Over the disabled button the stackpanel fires the mouseleave event ?!?!?!?<br />Button_MouseEnter&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;- we enter and then exit the last button<br />StackPanel_MouseEnter<br />Button_MouseLeave<br />StackPanel_MouseLeave</p><p>&nbsp;In SL2B2 the StackPanel didn&#39;t fired the Leave event we were over a disabled control contained in it...</p><p>so my question is:</p><p>Is this the desired behavior, or is it a side effect caused maybe by some tweaking in the event mechanics ? <br /></p>
