CR Plugin unresponsive

so, i have this issue. and a lot of people here have the same issue. and still no fix. someone say 'clean camera raw cache' and some say 'disable graphic processor', some say 'save file on the desktop and open from there' but actually the issue is far from solved.

ps doesnt care about those workarounds. i will post the always-working steps leading to the odd freeze. 

- open an image (not raw) or create new document.

- convert a layer to a smart object.

- open camera raw filter.

- the little window about camera raw progress is on front, click on the real camera raw window and the progress bar will go to background. camera raw now works.

- switch to whatever app you want, safari, finder, not important.

- once the camera raw window looses focus, is will not work from now on. buttons are greyed out, even ESC on your keyboard will not work. the only way to come back to your image is to force quit photoshop, and open a saved copy.

raw images opened with ps let you work on camera raw even if you switch app. and when you actually open the object and re-open camera raw, it still works. so it seems the problem is just the plugin on non-raw images. if adobe sais 'do not use camera raw on smart objects, use it only on raw images' disabling this feature on non-raw, fine. not really, but it could be at least some response. 

i've seen a lot of posts about this bug, some are like 2 years old.

can we hope for a proper solution? or do we pay real money every month for something broken?

for now, pleas SAVE before open the filter, and nver let it lose focus. no, you cannot check you e-mail. no, you cannot browse the web. no, you cannot change song. just work. focus. and save.

shame.
