Hey Ramsey. I had the same problem too. The following is the response I got to correct it...it seems to work. Good luck. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Nicholas Masse, M.Sc.

I followed the cook book on the Mathworks page and then entered "feature('JavaFigures',0)" and it worked perfectly. Thanks a lot, Jack Darren Gitelman wrote: Hi Dan/Jack/Nicholas Edit boxes in R14 have had a number of problems. This link identifies a problem in one m-file when tabbing out of an edit box. http://www.mathworks.com/support/solutions/data/1-XOUGD.html?solution=1-XOUGD I've also seen problems in WinXP on multi-line edit boxes. TMW suggested disabling the JavaFigures feature. feature('JavaFigures',0) I don't know if it will help you, but is probably worth trying.

(of course I have entered a contrast name and parameter) Any suggestions? Best regards Ramsey
