I have several databases and they're saved regularly. I also have another ubuntu server running on a virtual machine for testing.
When I use the account module to create an invoice... and I want to add a product to the invoice lines, it opens a new window where I can search and choose a new product. I can say then "Save & Exit " or "Save & New".
Now my problem is:
When I recover such a saved database and load it up on the other ubuntu server running on the vm, this dialog is not shown. Instead I can change the invoice line directly without opening another window.
Is this normal behaviour? Is it possible to switch it back to "normal". Is it because of a module update? However, no modules have been updated as far as I know.
