pXent_enable() and entity event

Hello
I run into to following problem. If I disable physics of an entity with "pXent_enable(ent,0)" function. The event function does not work any more when I able physics again with function "pXent_enable(ent,1)". Before disabling physics event function works just fine.

Should I set a some other flag also to get event function work again?
thanks in advance

I was able to solve this, it seems that one has to set collision flag again with "pXent_setcollisionflag()" function and then event function starts to work again
