Hi Ian:
1) The current version of IC is single-currency but the multi-currency version will be released very soon.
2) Edit the GridView icon and change the "Target" file name. Add a "/c" at the end. For instance, you might have the following "C:\Softrak\GVWin\GVWin.exe /c".
3) There is a P/O product that works with Adagio called "Purchase Orders for Adagio" from Purple. It is designed to be data-compatible with Inventory Receipts. I don't know about multi-currency support.
4) The brand new release of Adagio OE allows invoices and other documents to be e-mailed.
