I have been using Quicken since inception (over 25 years or so) and have been enjoying its features. I just recently upgraded to 2015 on my Windows 7 laptop (plenty of RAM). My experience so far has been dreadful for the following reasons.
1) In the register, the screen is having some spasms for a few seconds until it's ready for input.
2) When you try to enter a transaction, the cursor ends up on transactions you never intended to change plus a few spasms to go.
3) I setup my banking accounts for online updates and authentication with my banking institution has been a hit and miss. I had to resort to the download approach from the bank itself like I use to.
4) It's frigging slower than any other previous versions.
5) I desperately want to go back to Quicken 2014 or any other previous version.
Having gone through my email history for a download link, they all pointed to Quicken 2015. HELP!!!
