I have edited the post title so you are more likely to receive help, we get hundreds of posts on the Photoshop forum and "please help me" may not get read
- plus I recommend you describe the issue, also note your computer system and software version, some users are really wary about watching videos for fear of a virus or trojan.
You'll have noticed that A LOT of users on this forum are reporting issues with the latest Photoshop update.
I hope this helps thanks neil barstow, colourmanagement.net :: adobe forum volunteer [please do not use the reply button on a message within the thread, only use the blue reply button at the top of the page, this maintains the original thread title and chronological order of posts]
