[ JDK VERSION : 1.6.0_07 ]

In the "Categories" tree in Java Application Project Properties
Windows when I select the "Groovy" node and check the "Enable Groovy"
check box to enable groovy their is no way to uncheck "Enable Groovy"
option since that checkbox get disabled and when Canceld the
Properties window since their is no way to uncheck "Enable Groovy"
selection it is still persisted with checked option event when
Re-Iterate these steps again.Even if I close the project and reopen
and follow the above process the "Enable Groovy" option is still
disabled (checked) and no way of unchecking that option. This is
realy annoying. I have to restart the ide to get the "Enable Groovy"
option checkbox enabled.
