Hi Sagi,
I remember that there was a bug fix for this long time ago. Please note that 12.3 has reached end-of-maintenance and end-of-support. I strongly recommend upgrading to V21 or V24. If you have to stay on 12.3 for some reason then please upgrade to 12.3.10HF2, which is the last ServicePack to 12.3
Regards, Markus
