We try to select Assign or convert, and there is no way to have convert option. All times that I select, and open dialog again, Assign is selected.
Ok launch CorelDRAW but have no file open and grab captures of the color management dialog please.
I recorded my screen to show.
See that I have an open file, tried several times to change the option and it did not accepted.
I changed other options in Color Management dialog and it accepted.
And in the online help there is no mention about this feature.
I'll post screen captures of my settings later.
Here are my default application color management settings for Draw
Here are my Photo-PAINT default application cm setup
These are my application default settings. The settings in the document tabs should move and allow you to convert or assign, if they are not doing so there's some issue. If this is one specific document can you please share that document?
