Setting the RowSource property of a list or combo box object to a long string
causes Visual FoxPro 3.0 to report an error message or to shutdown. The behavior
depends on the platform Visual FoxPro runs on. In the Macintosh version, the
following error appears:

  Unknown Error Code 1482162264

And the Debug window highlights the following line:

     This.Combo1.RowSourceType = 1

In Visual FoxPro 3.0b for Windows running on Windows 95, the program shuts down
after displaying the following error:

  This program performed an illegal operation and will be shut down.

After pressing the Details button, the following error appears:

  VFP caused an invalid page fault in module Kernel32.dll at <register
  address>.

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 Visual FoxPro 5.0
for Windows.
