Hi all,
As far as the issue regarding the backward and forward compatibility is concerned, there is a definite issue with opening files in the newer version from the older versions like optisystem 10 and optisystem 13. I have seen many complaints regarding it and i hope optiwave will take good care of it in best possible way.
It will be also worth mentioning here that optisystem 14 for 32 bit machines is not yet available but yeah looking forward for that too.
Regards
