TControl.MouseMove - ssLeft mouse shift is never present

Original Reporter info from Mantis: Dibo

Reporter name: Krzysztof Dibowski

Description:

Hi,

Seems like all mouse buttons (ssMidle, ssRight) are present in mouse move event except ssLeft. Is it consumed by drag&drop or something?

Regards

Steps to reproduce:

I used TPaintBox.OnMouseMove event which is fired by TControl.MouseMove

Run attached demo
Move mouse over paint box and keep down custom mouse buttons. You will see which button is pressed by different color and message. Only ssLeft is never present
