I've encountered two different problems that I believe are bugs, both relating to footnotes. I've looked for evidence that someone else has reported this, but haven't found any.
This is the first problem:
Footnotes, if they are particularly long, are sometimes truncated in the Power Lookup window.

I've adjusted the program scaling and the text size, but this does not make a difference.
A second issue with footnotes is affected by program scaling. I like to have the program scaling at about 160%, but when I do this, long footnotes do not display correctly. The little window that opens up will not scroll down all the way:

Notice that the scroll bar slider actually partly disappears, and this is as far as it will go. There are two full paragraphs of the footnotes missing, which are visible when program scaling is set to 100%.
