Question Forms behave strange

[VB.MAN]

Hello,

I've established a new VS 2008 environment, after my first environment is gone (Windows was crashed).
I copied all sources into the new one.

Now I have a strange behavior: All lines shapes, frames and group boxes are not seen on the designer, but when I build and run the EXE, I can see all of them.

Do you know the reason?

I'm using "Microsoft.Visual basic.Powerpacks.Vs" reference and it's loaded, but it may cause the problem.

Thank in advance

 

[VB.MAN]

Hello,

I'm developing with VB.NET 2008.
One of my host was crashed, so I take the files and keep development on another host. But now something strange is happening:All frames, lines and shapes are disappeared on design-time, but are seen normally in runtime.
Please see the attached screenshot (Upper is design-time, lower is runtime).

How to fix it?

Thanks!
