When using a type/text area in PS my keyboard arrow key's sometimes just stop working. There's just no more feedback and I have to restart PS to 'fix' the problem. This is a very annoying bug which really degrades my productivity!
The CC software has become so friggen slow and bloated, it's a wonder they can find any bugs at all. I fire up CS4 on a occasion to reminisce the days of lightning-fast design potential...then quickly saddened and depressed on arrival back in 2015 with my 'slow' 5960x processor, 'measly' 128GB of memory, and 'god awful slow' GTX980 that all seem to struggle in unison just to make Photoshop CC respond about as fast as it did on my old Mac IIfx.
If you have a reproducible case that you can show me, I'd be more than happy to pursue this for you. We haven't been able to find one in-house and none of the users have either.
