FastForward.NET

Description:
FastForward.NET crashes with an unhandled exception upon attempting to change the Polling Interval in the Server Configuration Pane.

Steps to Reproduce:
1. Open the Settings Pane (File->Settings)
2. Using an existing Server (See below for our server config if this matters) Select and hit the Configure Button. This will open the Server Configuration Pane.
3. Change the Polling Interval to a new value (Our Default was 5, we are attempting to change it to 30)
4. Hit the Ok Button in the Server Configuration Pane.
5. Now Hit the Ok Button in the Settings Pane. This should produce the Unhandled Exception.

Environment:
- Windows 7 Enterprise x64
- CruiseControl.NET Server is 1.4.4 SP1, connected to via .NET Remoting on the local network.
- FastFoward.NET is version 0.5.2009.97
- The only plugin installed currently is the System Tray Monitor.

Existing Issues?:
Looking at your Issue Tracking system there appear to be similar issues within the Settings Pane; but none describing modifying the Polling Interval setting.
