SYMPTOMS :
You use roaming profiles that are shared between Microsoft Windows 2000 and Microsoft Windows XP Professional. When you run Microsoft Visual FoxPro 8.0 or an application that is compiled in Visual FoxPro 8.0 on a computer that is running Windows 2000, you may receive a C0000005 error.
CAUSE :
This problem is caused by the changes that Windows XP makes to the roaming profile to handle the drop shadow visual effect that is available in Windows XP. The problem does not occur if you run the application only on computers that are running Windows XP.
RESOLUTION :
To resolve this problem, download the DisableDropShadows.exe file. The DisableDropShadows.exe file turns off the drop shadow visual effect in the profile. Run the DisableDropShadows.exe file before you start Visual FoxPro 8.0 or a Visual FoxPro 8.0 application on a computer that is running Windows 2000. The DisableDropShadows.exe file accepts the name of any executable that you want to run as a parameter. For example, you can start Visual FoxPro 8.0 by using the following command line:
DisableDropShadows \Vfp8.exe
Note is the directory where Visual FoxPro is installed. If the directory has spaces in it, enclose the parameter in double quotation marks.
The following file is available for download from the Microsoft Download Center :
