Looks like Manager desktop uses a different random port each time it starts (visible in the address bar when accessing Manager through a web browser) eg
http://localhost:54274/businesses
http://localhost:54274/suppliers?FileID=14e111ef-dcb5-4a33-9029-12147b983a19
where 54274 is the port number used when running Manager this time.
and 14e111ef-dcb5-4a33-9029-12147b983a19 is the FileID of “Northwind”
On my Windows 7 Laptop I can
- Start Manager
- Open a Manager page in another web browser (eg firefox). Or better still open the working set of winidows in different tabs
- Minimize Managers normal window (so only the web browser shows)
- Put windows to sleep
- Wake Windows and re login to my windows user account
- Confirm Manager is still using the same port and web browser tabs still work as desired
Hopefully this works for you. Unfortunately bookmarks wont work as a dynamic port is used.
