random scrolling when double-clicking in Edit Data window

pagadmin3 1.10.0, GNOME Ubuntu 9.10, 64-bit:

Sometimes when I double-click in a field in a Edit Data window, the rows scroll to somewhere else, sometimes completely away from where I'm clicking.

Scenario for me:
1. Look at a table with about 30 rows (more than fit in Edit Data) and two columns
2. Scroll to the last row. Double-click in the last row in the second column
3. Scroll to the first row. Double click in the first row in the second column.
4. The Edit Data window will scroll to the last row on its own.

I don't know if there's anything special about the number of rows or columns: I suspect not. Sometimes I cannot quite duplicate this, but just playing around will usually cause it to happen. Sometimes the jumping scrolling is only a few rows as opposed to going to the top or bottom, depending on where I was and then where I click. Seems like a position indicator is not being updated.
