Apologies for the vague title, not sure how to summarise the problem...
I'm creating a dashboard report showing server state for a group of SQL servers, the problem is that the links for the drill down reports are slowly moving downwards in each row. Hard to explain in words but hopefully the images may help:
This is the initial load, the link is highlighted within the square.

As you move down the grid the link location is dropping:

After 8 rows the link is no longer visible on screen and cannot be selected.
This is apparent in IE8, using SSRS 2008 R2 the report doesn't load in Chrome (no idea why).
Does anyone have any idea how to prevent this from happening?
Thanks in advance, Tim
