copy and paste is not working in zoho spreadsheets under IE

copy and paste is not working in zoho spreadsheets under IE

when you do the following in Zoho sheet under IE:
1. double click on a cell which contains text or whatever
2. select all text in the cell or use (Ctrl+A)
3. copy the contents
4- go and paste the contents into another cell
5. the pasted text will appear only on the value bar above (for seconds) and not on the cell, so you lost the pasted text.

could you help me on this issue?!
