Are there any fixes/solutions to resolve this issue? With over 300 companies listed it takes a considerable amount of time before the list is populated with the results? This was only first noticed in version 27 but can see that the issue has moved into version 28 as well. It takes less time to scroll through all of the companies than it does to search for the 1 company needed! 

I've also tested a clean installation on a new VM (and Win 10 non VM) with only 5 companies on it and you can still watch the cursor slowly entering in the characters well after they've been typed. Everything else in Sage is smooth, just searching for companies after the splash screen.
