[3.1.7] Vassal freeze when module open from file manager


I’m with XP Pro SP3 with 2 GB of RAM.

When I double click on a .vmod file, Vassal is open and the module too. But when I start a new game, the board is never shown. I need to minimize the window and reopen it to see the map. And then Vassal is very slow.

If I open Vassal and then I open the module from Vassal, I have no problem, the map is correctly shown and there is no slow processes.

I’m the only with this little problem ?
