NOT open another instance?

Hello,

When I run the Arduno IDE, an empty sketch opens. When I then open a sketch, a second instance of the IDE opens. How do I stop this? When I open a file, I want the file to open into the same (first and only) instance I opened the file from.

I noticed this too and added a google code issue some time ago: http://code.google.com/p/arduino/issues/detail?id=837&start=300
Not sure it has priority as there is a bunch of issues to resolve.
