Not sure why its not working for you. I haven't had any issues. I'll check the patch. Regarding the font size/location, I tried to mimic what was already implmented in hte daily so as to not clutter. Attached is a screen shot of what I'm seeing in 1024x768 . I wouldn't expect to many people to use screen resolutions < 1280x1024. Either way, except for the seconds place in the Total Row, All the data seems visible. The seconds could be fixed by Abreviating Total to Tot: or simply T: in keeping with the style of first letter indicates the meaning.
Maybe an acceptable alternative is to make the default option to not display the Summary data. That would allow users with higher resolutions who care, select it and those who have lower resolutions and don't want it leave it off without worring about it cluttering their screen. I'm not against the tool tip idea but personally I like to see what my recent progression has been and the calendar view makes this a convenient review and is easier than having to go into the statistical viewer. Also, the initial tool tip doesn't respond as fast as I'd like.
Though I like having the statistical viewer, I find it is slightly less convenient then just looking at the data in the Summary block. To compare Distance/time/Calories for the last 4 weeks, I have to go through lots of button clicks to get the same data.
If you send a screen shot of what you are seeing, that may help me understand more.
