What does this error message text dump mean, please ?

[ibr_remote]

************** Exception Text **************
System.ArgumentOutOfRangeException: StartIndex cannot be less than zero.
Parameter name: startIndex


Is it something to do with my way of naming my folders and files ?

IS that the whole error message? And when does that error occur?

Hi,  The entire error message is copied below.  It happens only when I do certain searches, and I don't know what makes it happen.  Some searches work fine, others don't.  I am using a local stand-alone PC running Windows XPsr2. My runtimes are on external hard disk drives.





See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (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 computer
rather than be handled by this dialog box.
