IIRC the plot verb will re-use the previous plot window. If you have closed all forms and but wd'qpx' reports some plot form are still there, then something had gone wrong. try wd'reset' which will close all window created by wd commands and should reset to a clean state.
This does not fix the problem but may be better than reset a new J session.
