excel export problem!! illegal characters..

Hi to the guys at zoho,

I have a sheet with names, urls, numbers.
when i tried to export this table, it wouldnt export. there was no window.

I guessed there might be illegal characters/objects in the url field.
After creating a custom view without the URL column, I was able to export the table.
On re-enabling I was unable to.

Also.. generally we copy paste the url into the field, as against typing it in.
And copying from a web page could capture other things on the clipboard apart from text. Would this be the reason for this. If I pasted extra stuff in.

And once or twice i've noticed the form getting distorted .. and text getting pasted ONTO THE FORM.. outside the field.. following a paste command.. after clicking mistakenly on the form(white space).

I hope this query has been clear.

Thanks
