Version 'CONTRACT'

Hello.

I have to run OFS commands under the authorization of credit contract. I use EB.SET.NEXT.TASK in AUTH routine to launch mainline routine to execute OFS strings using GLOBUS.MANAGER.

Operations thread:
LD (F5) -> LD.SCHEDULE.DEFINE (F5) -> Run AUTH routine (execute OFS commands)

All operations are executed successfully but as a result system launch empty version with caption 'CONTRACT'.
If user doesn't close this version and tries to perfrom any operation system generates error modal dialog with message:

A run time error has occured
Function name: TOOL_BAR
Error message: 9 - Subscript out of range
SOURCE: DESCTOP
At line no : 0
Choose OK to continue or CANCEL ot terminate GLOBUS

To continue the work user has to terminate GLOBUS and login again.

Do you have any idea about the cause of this error?

Thanks in advance.
