NAV 2016 - Crash after using a report print preview

Hello,

We are currently working with the new NAV 2016 and ran into the following problem:
To reproduce I am doing the following:

1. Start the client with the profile: "Einkäufer" / "buyer" - Profile ID: 9007
3. At the RTC go to the report Tab and launch any report
4. Click on preview
5. Close the preview windows
6. Launch the report "Vendor - Top 10 List"
7. In the Preview Window I am only able to see the first line "Show: Purchases (LCY)" with a red box around it
8. The Window will not finish loading and NAV will crash without an error message

Another error that occurs before letting it crash is, all Menu buttons (the windows standard buttons) will view rectangular and white. Not round and grey any more. Here the screenshots:

Normal Buttons:


After print previewing:


Crash Screen:


This happens for us only on the following machine:
Windows 7 64 Bit
8 GB Ram
NVIDIA GeForce GT 740

Drivers are up to date.

We also have another problem regarding the print preview, which is not machine specific. I will open another topic for that one though.

Thanks in advance for any help!
