Restore window size

[paiiou]

I have at present a small problem, not grave, but very boring in the long run.
I play the sometimes with aisleriot.
With Mageia 1, the size of my window is automatically recorded. In the following play, the size is restored.

With cauldron, it is not any more the case. It is moreover the same there with the other applications.

I use the Xfce environment, but it is the similar with Lxde.
On the other hand, with Gnome the restoration is correct.
I tried to find the mechanism of saving and restoration.
I find nothing. An idea?
