Just started using Sweet Home 3D version 3.4. Looks great but it doesn't render properly on my system. The 3d pane appears anywhere and is unstable. Also the menu and tool bars often disappear, although they sometimes reappear incrementally if I pass the mouse over where they should be.

My setup is Dell Inspiron 1525 laptop with 3 GB RAM, Intel graphics accelerator, Vista SP2, Java 6 update 31.

Grateful for advice how to get SH3D working properly.
