If CC Libraries is open while I am working...
I've seen a few people report on this, but many of them were "closed" issues.....but if I have CC libraries open while I am working at all, it creates massive lag and the program will unexpectedly shut down frequently during use (2-3 times an hour). It is almost to the point of being an unusable app (while CC libraries is open). No problems with lag when Libraries isn't open, though.
Libraries connects quickly and otherwise does what it should be doing, other than crashing my program every so often!
I'm on W10, most recent version of XD as of 10. 10. 2017.
Not sure how we missed this one! Apologies for the delayed reply.
