Version 4.6.0.0 released 29th July 2015
The software now merely gives a warning if you try to connect a market to an Excel worksheet name that already exists (in a workbook that is already open in Cymatic), whereas previously the software prevented the connection to try to ensure that you didn't connect two markets to the same sheet.
This change was necessary to enable you to save complex workbooks that contain multiple worksheets, then re-open the workbook in the future and connect markets to the previously saved multiple worksheets, without being stopped from doing so.
Obviously in each workbook, you will have to use unique worksheet names and you should ensure that each sheet is only be connected to one market.
No warning is given if you connect a market to a worksheet that it has previously been connected to but from which you temporarily disconnected it (assuming the workbook hasn't been closed).
No warning is given if you connect a market to a worksheet in a workbook that isn't even open yet, because the software knows that no other markets could possibly be connected to it already.
Kind regards,
