The fact that you are using "align left" leads me to
believe that you are using the XYLayout layout manager.
That's fine for getting things initially laid out, but
you are encouraged to switch to some other layout
before running.  My guess is that the coordinates
for the objects which disappear are somehow getting
set to some location off screen.

Take the time to learn how to use the GridBagLayout.
Yes, it is difficult, but the rewards will more than
compensate for the slight pain of being disciplined
to learn it.


Also, you don't mention which version of JBuilder
you are using.  If it is 2005, make sure that you
have downloaded and installed the most recent
update (update 4, I believe).  With 2005, the
UI designer is new and there were some significant
issues with it which were mostly corrected in the
various updates that have been released.

At this stage of the game, I'm not using any layout manager
<null>.  This problem happens when I shift click the items on 
the design tab just to get things straighten out.  After 
reading and going through all the layout tutorials, and from 
what I've read, I plan on using GridBagLayout - if I can get 
away from restoring from backup every other adjustment.

Which brings up another question:  Is there a facility for
restoring from the backups?  I've just been doing the cut-paste
thing.  Doesn't seem real elegant.

As far as the update goes, I'm less than 30 days on the
version I have.  How would I know what/if I need?  There is
nothing in the help or on the main menu.

BTW - Thanks for your help.

You don't say which edition (Foundation, Developer, Enterprise)
you are using, but at least in the latter two, there's a "History"
tab at the bottom of the editor pane.  Once you click on that,
you'll see a "Diff" tab.  Pick the two versions you want, and
undo changes as needed.

The About box should give you the build and update numbers.
The build should be 11.0.320.0 and the update should be 4
for JBuilder 2005.
