Office Plugin freeze Excel during Save

Office Plugin freeze Excel during Save

Hi all,

I am facing with the following problem.

When I click "Save" from Zoho Add-Ins, the status bar of Excel 2007 keeps saying "Reading Workbook......." and stays there forever.

Anyone know what's the cause of this problem ?

Here is what I did
1) Click Login from Zoho Sheet
2) Click Open to select a file from Zoho Server
3) Edit certain cell from within Excel
4) Press Save
5) Excel freeze

Please help
