I use 
* expand tabs to spaces = false
* tab size = 2

* jdk 6 update 1

When I open RC1, it remembers my last selected tab like it should, but that tab displays tabs at 8 spaces  instead of
just 2.  All other tabs display correctly and switch between tabs does not cause this tab to fix itself.  Everything in
this tab works exactly as I would expect, if I had chosen a tab size of 8.  (Editing, scrolling, ...)  However, as I
chose a tab size of 2.

Reformatting the code also does not change the tab size.

If I go to tools->options and then immediately press cancel, the tab repaints where it needs to (behind where the
options dialog was) with a tab size of 2.  This causes artifacts, but scrolling around enough at this point will
eventually fix the repaint issues.  And now everything works exactly as I would expect, with a tab size of 2.

All other tabs appear to be unaffected.

Work arounds (that all are a bit annoying)
1) After restarting netbeans, always close the initial tab and then re-open it
2) Live with the huge tab size
3) After restarting netbeans, always open and the cancel the options dialog
4) Show the "Start Page" page on startup (however closing the start page does not put me on my last used tab from the
previous session, making this option less tenable)
