TAB traversal works fine for me in these dialogs. Can you test manually, please?

Which breakpoint type does the accessibility test refer to?

These issues were either fixed or were invalid, I can reach all of the mentioned components through tab treaversal now on:

Product Version: NetBeans IDE Dev (Build 200807090008)
Java: 1.6.0_10-rc; Java HotSpot(TM) Client VM 11.0-b13
System: Windows Vista version 6.0 running on x86; Cp1250; cs_CZ (nb)

Therefore I'm setting this issue to resolved worksforme - feel free to reopen it if there are any further problems with
accessibility of in these dialogs.

Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
