I tried to attach a file to a Purchase Receipt.
I click on the button USE EXISTING for showing me the receipts that are already stored in the Receipt Hub. I type in a search word and the results show below in a drop-down menu. However, as soon as I hover the mouse over it or press the cursor button on my keyboard to select one of the options the whole popup menu disappears. So I can’t attach the file.
This seems to be the case with Firefox 47.0 as well as Safari 7.0.5 (Mac OSX 10.9.4).
To work around it, I had to get it out of the receipt hub and upload it directly into the purchase receipt.
