Hi Loïc,
I found it out by extract my program.
So the problem will be isolate.
The version of our environment is change from VDF14.1 to 15.0.
In VDF14.1 I can close my application without errors. In VDF15.0 it seems to hold the gdpicture open and the error will be occur.
The thread
http://forums.gdpicture.com/post5382.html?hilit=closeimage#p5382describe my problem very good.
I can only close the gdpicture at end of application.
With Terminate () the gdpicture object will be closed.
In our application are about 30 gdpicture objects, I don´t know which are open at end of work.
In the sample the terminate() will not be used. Should the Image closed (Imageclosed) use before send the terminate() ?
