[Newbies] Problem encountered when reading help files
Hi Jerry, You have found a bug. One way or another. The best thing to do is to plant a report on mantis. Then to increase attention, write the mailing list and refer to the mantis report.
Yours in curiosity and service, --Jerome Peace
Here are the faq's
FAQ: Is this a known issue ? Where is the place to report bugs (or check if some have already been raised) ?
The best place for this info would be to start a Mantis report. (You can get a mantis acct freely and easily).
A good place to start is:
http://bugs.squeak.org/my_view_page.php
Mantis provides a patient persistent way to focus on an issue. I use it to accumulate data on a problem until a solution can be found. It provides a place to alert the community to a problem; -accumulate facts and clues from the analysis; -publish preposed solutions and get feedback; -get solutions harvested and included into the main stream.
This FAQ is available at the Squeak wiki site. http://wiki.squeak.org/squeak/Mantis%20FAQ%20and%20Tips aka: http://wiki.squeak.org/squeak/5912 Mantis FAQ and Tips

SequenceableCollection>>last answers the last element of the receiver, and is implemented as: ^ self at: self size.
It is an index error, when size is 0.
I assume this is a design choice, rather than a bug; but I'm too new to know. Anyway, in 3.10.2, when I tried the menu path "World::Help::Preferences::Help!", it threw the exception, apparently because of an empty aHelpString. So I guess either Preferences>>giveHelpWithPreferences should be checking for empty stings, or the source data (the help strings) are improperly formatted. I didn't know what else to do with my new found knowledge, so here I am.
