FIX: Relationship Between Tables May Cause ICE or GPF

WINDOWS   | MS-DOS

The information in this article applies to:

• Microsoft FoxPro for Windows, versions 2.5x, 2.6
• Microsoft FoxPro for MS-DOS, versions 2.5x, 2.6

SYMPTOMS

Under certain rare circumstances, setting a relationship between two tables causes an "Internal Consistency Error" message.

Notes

In the Extended (32-bit) version of FoxPro for MS-DOS (FOXPROX.EXE), the lower portion of the screen turns red with yellow characters. This portion of the screen contains random characters in addition to the "Internal Consistency Error" message.

In FoxPro for Windows, the following error message also appears:

   FOXPROW caused a General Protection Fault in module <unknown>
   FOXPROW will close.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in FoxPro 2.6a for Windows and FoxPro 2.6a for MS-DOS.
