Curiosity questions: UR Internals

[cnewtonne]

Kinook,
These are nothing more than curiosity questions. I'm in the process of finding my way around learning about the different programming languages mainly C# and VC++ and their associated IDE's. I would like to pose these questions and hope that you are able to address them...

- Is UR a .NET or native win32 app?
- what language did you use to develop UR?
- What IDE did you use?
- What kind of controls are these different panes? Are they 3rd party, MFC, or MS provided?
- Is UR considered an MDI app? Are the tabs simply child windows and if so, can they be managed using standard windows operations like min, max, cascade, tile, etc...?
- From your experience, had UR been developed with something like C#.NET, would be able to perform as good as it does today?

Thank you
