Question : Solution for shared excel

Dear expert

Im currently looking for a better solution for sharing a excel 2007 file to many users, for now the shared worksheed didnt work as well as it should, sometime users save didnt show up next day and sometime it crash...

Now im thinking of changing that to other solution, but im not sure what should i change to. Any advice would be good, and also shared excel in office2010 is there any improvement?

Thx
