Set default folder to open in FileToOpen

[MuppetReaper]

Hi all

I'm trying to specify a certain filepath (happens to be SharePoint) in a FileToOpen command, but it doesn't seem to keep the path when other people use it
the extract of code is below

Sub Get_Template()
    CurrPath = ActiveWorkbook.Path 'ThisWorkbook.Path
    SetCurrentDirectory "\\teamspace.intranet.group\"    
    
    FileToOpen = Application.GetOpenFilename _
        (Title:="Please choose a file to import", _
        FileFilter:="All Excel Files *.xls* (*.xls*),")

this always used to work fine, but seems to have stopped recently
We have a mixture of PC's on XP and W7 with Excel 2007 and 2010 - is this part of the problem?

Is there a way to make this go the the folder specified?

thanks
