Warning solo en Windows 98

Muchas gracias por las respuestas sobre ShellExecute. Anda muy bien con
System.Diagnostics.Process


Ahora, otro problemita: Un sistema pequeño no muy complejo anda
perfectamente en Windows XP pero en Windows 98 el motor .NET me muestra un
warning con el texto que copio abajo.
El warning me da la opcion de Continuar o detener. Si le doy continuar el
sistema sigue corriendo y aparentemente anda todo bien.
El Windows tiene instalado el .NET framework 1.1 y ademas el patch
NDP1.1sp1-KB867460-X86.exe
Alguien sabe cual puede ser el motivo del problema? alguna pista?


gracias

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.
