Strange ... we haven't seen that before. I think it might be due to the Project Properties window being visible and the Rake window being undocked.
Try docking the Rake panel to the bottom set of tool windows. That should stop it popping up every time VS thinks there a context switch.
You're a bit out of date on the releases. 2.1 is our 'official' release. There aren't very many bug fixes between 2.0.1 and 2.1 but here's the release notes:
This is Ruby In Steel 2.1.0 build 1280.
Notes:
1) The synchronization between RubyType and the ruby interpreter has been improved so that a type mismatch (debugger failing to load, etc.) is minimised.
2) JRuby 1.6.4 for Rails 3.3.1 has problems with SQLite3 - it cannot build the Gem - when running under Windows.
3) Ruby 1.9.3 is supported
4) Improved handling of exceptions by the debugger (1.9.2 and above)
