Two users have begun seeing a sporadic error on a block of code that has never caused any issue before. One user gets the error about every 10th record being added. The other user has only gotten the error once.

The error being returned is:

         Error # : 1429
         Message : OLE IDispatch exception code 0 from Visual FoxPro for Windows: 13 :Alias is not found...
     OLE Message : 13 :Alias is not found.
   OLE Exception : 9
            Code : SELECT ourAlias1.cFieldN, ourAlias2.cFieldN   FROM  abc!ourAlias1  INNER JOIN abc!ourAlias2  ON  ourAlias1.iPrimaryKey = ourAlias2.iForeignKey WHERE  NOT (ourAlias1.lDeleted ) AND  ourAlias1.iPrimaryKey = ( vp_iprimaryid ) into cursor Viewcalv59
          Method : loadrelations
          Object : xyz
            Line : 24

Line 24 is:

Application.RequestData(cAlias)

The aliases in question do exist, are already in use, and can be browsed if stepped through that code. We have not been able to replicate the error. Originally it happened at one client's site and we assumed it was a setup issue on their computer or network. However, it's now happened at a second client.

Has anybody had any experience with this error?
