Question : Problem: Win XP Dual monitor mode

I've 2 monitors connected to 1 PC (VGA + DVI cable).
The desktop graphics settings allow the following modes:
- Twin
- Dual Display Clone
- Extended Desktop
The modes further have the options: Primary/Secondary Device with Monitor + Digital Display as options.

What to take if I need the mouse to move from e.g. explorer on the right side to outlook on the left side, allowing to drag&drop files etc.???

Answer : Problem: Win XP Dual monitor mode

extended desktop basically doubles the width of ur desktop but if you maximize, say, outlook it will only maximize to one of the full screens
