Thanks for your interest. Here are some responses for you:

- No changes were made to either dotProject or Mantis. The code was developed via a dotProject Module and is entirely self-contained.

- The code is very stable. It has changed very little in 3 months.

- The only change you must implement is the addition of a table to your dotProject install.

- There is no plan to update the project indefinitely, but I'll look into it.

- Setting up a custom mapping (Feature -> New Feature Request) should be trivial.

- I have not been able to reproduce your error. The two databases are automatically wiped every few hours, so either a) this happened while you were using the system or b) this happened afterwards and now I can't duplicate it.
