I installed 8.1C and the hotfix POHFP20130608.EXE. I didn't even know it was possible to run 8.1B anymore since 8.1C overwrote my previous installation.

On Monday morning (yesterday), we had 3 users on PO.

• User 1 was receiving both negative and positive and had no issues.
• User 1 also opened an existing receipt that had 2 vendors. Vendor 1 was already invoiced. Vendor 2 was still at the delivery note stage. A line for GST was added with no proration. The tax on the total screen was adjusted by 1 cent. The invoice was posted with no issues other than the tax change was not saved, even though the hot fix was suppose to correct that.
• User 2 was creating PO’s and could not email or print.
• User 3 was receiving negative and could not print.
