BUG REPORTS
~~~~~~~~~~~
When using version 1.50 thru 1.60, a bug causes the text line on the bottom
row of the first window scroll to shift left by 1 place. (It has been fixed
in version 1.61).
When using version 1.52 thru 1.60, an incomplete sign test yields an output
of 0.100 instead of 1.00, when the divisor and dividiend are the same. (It
has been fixed in version 1.61).
Version 1.61 displayed unreadable characters in graphic mode for writes via
interrupt 10h, functions 9h and Ah.
