It seems that for the last 2-3 EAPs my config and project files have gotten less and less compatible with IDEA.
I can not open the Project Settings anymore on projects created before 7020 or so. I can still use them... just not change any settings.
is this normal? I realize that at some point old project files can get in bad shape if they have been updated in many EAPs. Is my only solution to re-create my projects?
