One thing I discovered in December - The Excel Add-in for Excel 2007
does not work. There is a PTF avaailable for it.
Office 2007/CA v5R4/ - Failed excel.exe during data transfer with
cwbtfxla.xll
The link from IBM tech support describing the exact issue. It
mentions a PTF, but no other details after that.
