Cetin,
Thanks for immediate reaction. I have heard about this limitation (strange for 32bit system) and definitely some arrays will exceed 65000 elements. But what is astonishing me that before I spotted the problem I have been using also arrays which were biger than this limit. Additionally I can't find config.fwp in my system which should help in this situation a bit by proper setup. In fact I don't know how to use insert and use this file.
