Sub-Tasks hidden in the Task Board (Outline View) when displayed on multiple pages

See attachments for references.

0 - In Firefox 3.0.7
1 - Under the Task Board in Outline view
2 - Some issues are displayed on a second page
3 - [Second attachment] Some of the sub-tasks are hidden under more than one issue (GreenHopper does mention the right totals though)
4 - [First attachment] By changing my user preferences, I can get every issue to be displayed on a single page without any missing

Regards,

Martin
