edit bitmap from CDR

As of today, I cannot "edit bitmap" from within CDR.

I just dropped a png image into a CDR project, then I decided to do some editing before I use it in my project, so I looked to "edit bitmap" but the option wasn't available.

Not uncommon, if its not a proper bitmap yet...so I "convert to bitmap" ...and still the "edit bitmap" option hasn't become available.

I tired converting a vector object to a bitmap to see if the "edit bitmap" appears, but it stays grayed out.

I've only been working in 2018 for a month or two, but I'm sure I have edited bitmaps and would have noticed this problem sooner.

Has something happened recently that has changed this?
