Bug when entering or leaving opacity mask

[vpck]

I don't know when this started happening but it's recent. Most of the time, I can't enter Opacity Mask. When I manage to enter (after doing the same steps tens of times), then I can't exit it.

Steps:

- Select an object with an opacity mask

- Click "Opacity"

- Click the opacity thumbnail

At this point I should enter Opacity Mask mode, but it's not happening. If I repeat the same steps 5-10 times it will eventually enter it. At that point, if I try to exist this mode through the same steps (Opacity panel -> Left thumbnail), it will not exist Opacity Mask mode.

If I uncheck/recheck the Clip checkbox before clicking the thumbnail, it seems to work.

I've already restarted Illustrator and reinstalled it. It's something with a recent version I think.

@vpck I remember to have seen this reported. It only happens in the Appearance panel, but still works in the Window  > Transparency panel. 

You may want to report it here:

Thanks, this workaround seems to work for now. And thanks for directing me to uservoice, I wasn't aware of it. I've found a similar report there from 2 months ago, so it seems this is a known issue since at least 29.5. I hope it's fixed soon.

Good to hear that helped.
