Just-patched Excel makes calculation mistakes

One of the patches issued causes Excel to make incorrect calculations when a Real Time Data source is used

Microsoft last week told Excel users that one of the 12 patches issued causes the spreadsheet to make mistakes in some calculations.

In a warning posted, Bill Sisk, security response communications manager, said that the fixes outlined in the MS08-014 bulletin "causes Microsoft Excel 2003 calculations to return an incorrect result when a Real Time Data source is used."

According to a more detailed addition to MS08-014, Excel 2003 Service Pack 2 (SP2) and Excel 2003 SP3 return an incorrect result -- usually "0" -- when a Real Time Data source is used in a Visual Basic for Applications function, or macro.

"If you have applications that leverage Real Time Data sources in Visual Basic for Applications functions, we recommend that you perform additional testing before initiating a wide deployment of the update," advised the new version of the bulletin.

Real Time Data was added to Excel in the 2002 version of the spreadsheet, and allows users to have data automatically pushed into a spreadsheet from a variety of sources, Web sites included.

"Our teams are testing a fix and will release it once it meets our quality bar for broad distribution," Sisk promised.

In the meantime, Microsoft suggested that users run any function containing a Visual Basic macro that refers to a Real Time Data source on each cell individually, rather than on an array of cells.

Last week, Microsoft rolled out four security bulletins that patched a dozen vulnerabilities, all in Office, including seven critical bugs in Excel under the umbrella of MS08-014. Microsoft did not specify which of the seven fixes "broke" Excel 2003's calculations of Real Time Data.

One of the patches deployed fixed an Excel flaw that had been exploited for at least two months in targeted attacks.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
