I was surprised to not see any recent posts on this.
While using Pro 2.7 I am having to kill the program in task mgr after it freezes on save. This happens when using local data, and with data in Agol and is not correlated with any other action I know of.
Pretty disruptive since it results in loosing all project work up to hitting save button.
The program creates recovery project when it's been killed in task mgr, it rarely has the work saved in the recovery file.
May start by reinstalling.............
