pretty simple to see, in the Select Package Groups screen - scroll to the bottom - click Hide Help - click Show Help notice that the listing has reverted back to the top, but the scrollbar is still at the bottom. This may or may not be related to the whole bug about the scroll list not going to the selected value, hence the new bug report
Will look into.
Will have to address in a future release.
Still present in Phoebe beta.
This should be fixed with our current code.
Mass-closing lots of old bugs which are in MODIFIED (and thus presumed to be fixed). If any of these are still a problem, please reopen or file a new bug against the release which they're occurring in so they can be properly tracked.
