QFE addressing problem related to sequential execution of operations is published

You can find it here. Here is what it does:

In Microsoft Office Information Bridge Framework Server 1.0 there is a bug that prevents the sequential execution of operation instances that call an assembly when the location is specified as a URL in the port such as http://server/assembly.dll. The first operation instance call is successful, but subsequent operation instance calls fail. This does not impact operation instances whose path in the port is specified with a UNC path. This hotfix fixes this bug.
