Not sure if this is norml or not, but all my users are running Windows XP. I have a Snap 4500 Server for file storage. I am getting complaints that "When we have 3 or 4 people that have this 8MB Excel file open, all of a sudden other people can't open it...Sometimes it shows as "hidden", and other times we can't even see it." I've already gone through the File Options>View>Show Hidden Files to make sure that wasn't the problem......Is it normal for a file to only be able to be open by a certain amount of people at any given time, or do you think it's the file size, or...??? ?? ??
