[izpack-users] How to gray "Previous" button & enable "Cancel" button in InstallPanel

[jungu zhan]

Hi,
I have settled the two questions, but I am not sure
this is the right way.

in InstallPanel.startAction method, change

parent.blockGUI();

to

//parent.blockGUI();
parent.lockPrevButton();

now it works, but it  possiblely leads to some
inconsistent states.
