Please can you try the changes below. I have tested here and they fix the ShortCutBar issue, however I need to understand the impact on users of the SigCjPushButton class before commiting these changes to SVN.

For users of the SigCjPushButton class the OnClick event has been moved from Mouse Down to Mouse Up. This should have no effect unless you have augmented / overridden any of
OnComMouseDown
MouseDown
OnComMouseUp
MouseUp
please let me know if this change impacts you


Change 1 – cSigCjPushButton.pkg – cSigCjPushButton class
Move “Send OnClick” from OnComMouseDown to OnComMouseUp

Code:
    Procedure OnComMouseDown Short iButton Short iShift OLE_XPOS_PIXELS iX OLE_YPOS_PIXELS iY
        Send MouseDown iButton iShift iX iY
    End_Procedure
 
    Procedure OnComMouseUp Short iButton Short iShift OLE_XPOS_PIXELS iX OLE_YPOS_PIXELS iY
        Send OnClick
        Send MouseUp iButton iShift iX iY
    End_Procedure
Change 2 – cSigCjShortcutBar.pkg - cSigCjShortcutBar_Item_Button class
Change the supper class from cSigCjComPushButton to cSigCJPushButton (remove Com)
Change the name of method OnComClick to OnClick (again remove Com)
You will also need to change the Use statement at the top from Use SigCjW_Controls.pkg to Use cSigCJPushButton.pkg

Code:
Class cSigCjShortcutBar_Item_Button is a cSigCJPushButton
 
    Procedure Construct_Object
        Forward Send Construct_Object
 
        Property Handle phMsg
        Property Handle phObj
