Hi. There was a code change in RC4 to fix an issue with the previous RC3. What happened was that in situations when the last line in region 1 is displayed, then all the other extra lines in region2, eg in your example 2 lines, will be squeezed into the space – and the font can become quite small and not legible.
If you do want to display all two extra lines in region 2, then it would be best to combine the two lines into a line. This change applies to both regions. Hope this not does create a problem for you but the change in coding had to be made.
