[pstricks] combine psTextFrame

[Marco Daniel]

Hello,

I want to create an environment like beamerboxrounded. So I want to use 
pstricks. In the following code you see the problem. The second 
psTextFrame do not have the right upper corners.
 Do you have any idea?

I would also use an other idea?

Thanks
Marco
