My MBP blew up so am on a temporary Blackbook and luckily all my important day to day docs are on my iDisk, no problem I thought... But something really odd is happening, when I try to open a spreadsheet with Excel (tried 04 and 08) it says "the file may be read only or you may be trying to access a read only location or the server the document on may not be responding". I can open the file with open office and ALL other file types open fine from iDisk (including Word and PPT). At the moment I am having to drag the files to my desktop edit them and drag them back to iDisk so all is up to date when I get my computer back. Has anyone had anything similar? Any tips gratefully received (apart from the obvious; ditch MS Office!). After first noticing the problem I set iDisk to keep a local copy on the temp machine but this made no difference.
