I'm using Quicken Version 6.4.4 (Build 604.41834.100) on an iMac running Catalina. I like to leave Quicken hidden in the background all day rather than quitting and reopening it. I've noticed with the latest build that this gives rise to a bug. If after some period of time where it's been in the background and I click on the refresh icon to update my accounts, I get a message box saying that this is an older version of my file, offering me the option of opening a different file, etc. So at that point I select Cancel, quit Quicken, and reopen it immediately and everything is fine...for a while until the bug appears again. This was not the case in the past. Please fix this.
