Help File won't display

Hello all,

I'm a long time AutoIt user but have not written a acript in a few months.

In any event, I opened SciTe today to modify an old script of mine and in the process i needed help on a function, so I pressed F1 to access help. The Help window displayed and the help subjects appeared in the left pane but nothing appeared in the right pane (where the contents of the selected item usually appear).

I've re-installed AutoIt twice and SciTe once but to no avail. I've also disabled all virus and firewalls and still no joy.

Does anyone have any suggestions?

Regards,
