Hard to fix without specifics.
LR CC is rock solid for me on OS X Yosemite.
Can you give us examples/screenshots/error messages of the issues you're encountering and details of your computer specs?
It would certainly help to know what version of Lightroom you are using, and what operating system you are using, and how much RAM you have in your computer, and a description of the difficulties you are having in a little more detail. Then it might be possible for someone to provide some possible solutions.
Each abnormal termination results in a full dump being sent to adobe, they should be well aware of the issues. the dumps contain all the info they need to track down the problems. thanks for your replies...
Thanks for the response.
I've never seen an abnormal termination by Lightroom so I cannot comment.
