A Revolution in Education
In regards to some of your problems:
1. I haven't come across this. When you change to text font/style do you the select save properties before beginning to type?
2. Very strange. I didn't know this.
4. I had the same problem occur yesterday. As a guess it has to do with flash. With version 10.6 there were frequently problems with flash, hence the new upgrade. From what I can work out, the larger your file the more likely you are to lose images within a flash file from the Gallery. Yesterday I lost images from 'Image match'. The size of my file was 44.2MB. I then tested my theory by creating a Notebook doc with multiple flash files (in particular image flash files) which was much smaller, 764KB. I've opened it multiple times and tried to lose images by flicking through pages quickly and shutting it down quickly but I can't seem to get the images to disappear. Until SMART fix the problem with a new release maybe keep your files smaller.
I have been using 10.7 for Mac since it was released. I did download the patch. Using files with flash seems to be much improved. The issue that I am having involves touch. Every morning, I have to orient the board,because the touch doesn't work or is way off.
I have re-downloaded Notebook twice and it works well for a while, then the problem reappears. Hoping that the next version addresses this.
This is what our rep told us. He said it was pretty common. Dust gets into the projector and stops the color wheel from turning properly. The color wheel is responsible for the reproduction of color on the screen. When faulty, this results in flashing red and green colors on the screen. Very trippy! It also meant that the projector shut down after 20 mins by itself. Perhaps from overheating. I'm not sure about that.
