Though not perfect, we have a temporary fix that we’ll be posting shortly. You’ll be now be able to resize by dragging the bottom right handle.
The file list on the Main portal page is using less than 350 vertical pixels while 1440x900 are available. Dragging the bottom of the drag-able box only makes the brown button area larger, not the grid.
An update to the servers was made a few minutes ago. Please logout, clear your cache, and log back in to try again. Please let us know if this resolved the issue for you and if yes, mark the response as an accepted solution.
We’ll get that resolved shortly. I think it broke when we updated the grid when we added sub-reports and gave it a hierarchy.
