[PUPSTAHS]

Ok I just tried that out... it seems to fix half of the problem. Now all-day-events are shown on the correct day, but if you click the link, it still goes to the day before.

So for example, before the fix an all-day August 14th event would appear on August 13th and link to August 13th, resulting in an error. Now it appears on August 14th on the mini calendar, but still links to the 13th, so there is still an error.

For more information, here is August 2004 on my mini calendar.

Original, unmodified install:
*12th - Midnight to 9AM
--Correct
*14th - All-day
--Incorrect, the 13th is highlighted/linked instead and the link points to the 13th
*20th - All-day
--Incorrect, the 19th is highlighted/linked instead and the link points to the 19th
*21st (8am) to 22nd (9am)
--Only the 21st is highlighted as having an activity, even tho the event extends over two days
*29th - 8am - 11:30pm
--Correct
*30th - All-day
--Incorrect, the 29th is highlighted/linked instead and the link points to the 29th

Now w/ your fix:
*12th - Midnight to 9AM
--Correct
*14th - All-day
--The correct day is highlighted, but the link points to the 13th, resulting in an error
*20th - All-day
--The correct day is highlighted, but the link points to the 19th, resulting in an error
*21st (8am) to 22nd (9am)
--Only the 21st is highlighted as having an activity, even tho the event extends over two days
*29th - 8am - 11:30pm
--Correct
*30th - All-day
--The correct day is highlighted, but the link points to the 29th, resulting in an error
