assign non rw owner when new ticket creation

[felix]

Hello,

I want to create a new ticket and directly assign an owner to it. But if the agent I want to assign the ticket to has no rw-rights (despite having "owner"-rights), i am unable to select him when creating a new ticket. When the agent has RW rights, it all works fine
In ticket zoom, after creating the ticket, I can change the owner of the ticket to agents who don't have rw rights. But this kind of cumbersome when tickets need to be created fast...

I've been checking sysconfig but nothing seems to be configurable at that point....

thx

an update:

when i want to change the owner (or responsible) wich hasn't RW rights i get the message:

Software error:

Invalid version format (non-numeric data) at C:/PROGRA~1/OTRS/OTRS//Kernel/System/Log.pm line 160.

For help, please send mail to the webmaster (webmaster@somenet.com), giving this error message and the time and date of the error.
