HotSpotImage loading/saving spots

Yes, I checked the Sample.

There the Image is predefined.
I have the Bug - reproducable - when I make at runtime a 
HotSpotImage.HotSpots.clear;
HotSpotImage.visible := false;

Load the same Picture again and then load the HotSpots of this from File. 

What I make in the Delphi IDE works fine. Only by loading and/or saving at runtime I have this Problem.

If you sill couldn't reproduce it, I can upload you a Sample from me.
