solved - 2.48a visible or not

i have a file with several objects and i use 4 viewprots

now in front view i got only 2 objects while i can see all the objects in othere
views

how can i see all the objects in front view?

i did chec k with H -key and alt-h and also the alt-b function

but cannot make all the objects appears in front view only
all the other viewport are ok!

alss check the outliner eveything is visible!

i did transfert eveything inot another file and it’s ok

but i still would like too know what going on with that file
and bring back all the objects i front view

problem solved

simply press on / for local view in that viewport! by mistake

Thanks
