Last column in grid is not displaying cell data in virtual mode - 2.5.2

Info:
- Using AW.Grid.Extended.
- AW version 2.5.2.
- 4 fixed colums and about 30 columns all together (wide!).
- 100-500 rows

Problem (this occurs in Firefox 3 and IE 7):
The last column displays in the grid, however the cell data does not. If I resize other columns smaller then the column data will eventually appear. Now, if I remove a few columns from the grid then last column appears with data. However, if I resize the other columns larger then the last column(s) data will eventually disappear. Very strange...

Solution:
If I turn off virtual mode then the problem goes away.

It looks like there is something wrong with column width calculation - grid 'thinks' that the last column is out of view and should not be rendered yet. One possible reason might be incorrect padding+border width if you are using standards-compliant doctype (i.e. you added the border but did not reduce the padding).
