When selecting the ranges I wish to use for Custom Error Bars on various
charts, Excel 2007 SP1 consistently and repeatably crashes. The crash occurs
as soon as I click on a worksheet to begin selecting the desired range. The
problem is not limited to a particular workbook or chart type.

Furthermore, the Custom Error Bar range selection popup window does not
allow copying/pasting of text. This prevents me from doing anything but
manually typing in the cell ranges I wish to reference as error values.
