buildid:
2.6.0.v20100412-0630

steps to reproduce:
1. new a report and new a style
2. in edit style dialog, choose hightlight -> add...
3. condition: 1 equal 1, highlight style: font color to red.
4. click ok.
5. check the highlight added in edit style dialog.

actual result:
the new added rule is selected by default. i can not de-select the rule.
as a result, the preview is not available in the edit style dialog until i close and reopen it.

even though i switch to the map tab then back to highlights tab, the rule is still selected and can not show the preview result.

similar issue with the map in edit style.
please check if this is xp specific issue. as i cannot reproduce in win7.
fixed it.

window7 doesn't have the problem.

and only the multiple selection table can do the deselection operation, so i set swt.multi style on the table of the highlight preference page.

the map page doesn't need change, it doesn't have the color property.
