I have the MyEclipse 7.0 All-in-one installer on Windows XP 32 bit. Mylyn is now part of 7.0 (or I added it as an MyEclipse plug-in). I imported all my old MyEclipse 6.6 settings where I had Mylyn 3 installed (and started with my 6.6 workspace).
My problem is that I can’t add a task repository in the “Task Repositories” view: When I right-click to ad add a repository, everything is greyed out. Only the local repository is there which I can’t change either – but I can add a task to it.
