Read-only items are not read-only

[Nobodo]

I copy a lot of emails into UR from Outlook.

Often when a set of instructions in an email need to be changed, I forget that I am viewing an email in UR and just start typing along, correcting the instructions.

UR gladly accepts these changes to the stored email, but then as soon as you go to a different item and then go back to the email, all the work you just did in changing the item is lost.

Shouldn't an item be read-only in the viewer if UR will not store changes to it? This is a situation that allows a loss of data but gives no warning at all that the data will be lost.

Thanks,
Mark.
