Notes does not open new windows (menus, properties etc)

On one workstation Notes is not working properly. It is not possible to open any secondary windows / popups, such as preferences, properties, print window, access control list, new database menu.This particular PC is running

Win XP Pro Service Pack 1 (German)

Lotus Notes/Designer/Administrator v6 (English)

Hardware

Shuttle SN41G Barebone

AMP XP 1800+

Onboard nvidea 128MB RAM

The system is really fast, the only problem so far is the Notes 6 installation, any ideas?

Subject: Notes does not open new windows (menus, properties etc)

Solved. Was due to some Nvidea tool settings. Don’t know which one it was, but after playing with dual screen settings and so on, Notes worked fine again.
