I'm having the same problem I thought it was a vista clich but maybe it's the upgrade. It's when you use the find key in order/invoices/credit notes. What happens is all the orders are not made available when you use the find function. So when you key in your order # to pull it up to process it can't find it and goes to the last one on the list usually an earlier number. All the orders are no longer made available. You need to keep closing this window and openning it again to have the orders appear. It's definately a problem that needs to be fixed since it's time consumming.

I see there is another upgrade to version 8.1C not sure is this was fixedin the upgrade. I'm using V8.1B right now
