Shared Sheet not updating for simultaneous users

Shared Sheet not updating for simultaneous users

Hello,

When two of us edit a sheet simultaneously, we don't see many of each other's changes and can overwrite cell without knowing there was data in them.

For example, Alice and Bob are editing the same sheet at the same time.

1) Alice types data in cell A5
2) Bob's view of A5 still shows it as empty, even several minutes later
3) Bob types data in A5, overwriting Alice's without knowing it.

Updates seemed to be more frequent for one user than the other. We tested this several times. Both users are using Firefox 2.x on WinXP.

We are just trying out Zoho for the first time, so we're newbies, but we're both IT professionals so we have some sense of what we're doing. Zoho is very impressive, but this bug is a big concern because it hinders collaboration and because of the risk of dataloss.

Thanks,
Tom
