Blender crashes when sizing it's window


I just installed Blender 2.79 on my Windows 7 Computer. Everything works fine, but when i resize the Blender Window, it crashes…

I use two Monitors on a Dell Precision m2800 System with an AMD FirePro graphics card. May be, there is a problem with this grapics card?!

I updated graphic driver, restarted the computer - but nothing got better.

Running Blender as an Administrator and switch compatibility mode to Windows 7 also doesn’t solve the problem.

Any idea?

There was a problem with the open GL driver of my grapics card. When i reinstalled the old driver of 2015, provided by the manufacturer of the Laptop, everything works fine.
