The company has posted an update to version 3.5 of Jet to its Web site. Jet is included as part of Microsoft's Access database, Office desktop application suite, and Visual Basic development tool.
Developers posting messages to an Internet newsgroup said the update does seem to eliminate the data access bug, which was first reported by CNET News.com.
The bug affects the way Access handles changes to database records. The bug causes edits made on one Access database record to be saved to another record. In other words, in a typical business application, the bug could cause information associated with a particular customer or medical patient to be attached to the wrong account.
The bug discovered last month, is traceable to Jet and affects Access 2.0, Access 95, and Access 97.
The company last month posted a bulletin to its Web site that documents the bug's behavior and suggests a method for resolving the problem.
The update to Jet is a file that contains new versions of two dynamic link library files included with several Microsoft applications.
