Something I do quite often is copy a hex value and paste it into the Hex field on the color chooser.
Unfortunately this feature has been extremely buggy for quite some time. I first noticed it on version 7.5.13 and we have since upgraded to 7.7.5 and the problem still occurs.
Sometimes it works just fine.
Sometimes if I click in the box I can’t paste anything in there or even edit the value. I’ve noticed that sometimes when I’m trying to enter a value the text I’m typing goes into the Angle property field on the Property Editor pane. Usually when the dialog is in this state pressing tab doesn’t move between fields on the dialog like normal but instead selects different properties in the Property Editor pane. Even if those properties are not color fields the color dialog remains open. In this case I have to close the color chooser, select a different component and then go back to the original component and try again. Often that does NOT fix the issue. I haven’t found any process that consistently makes the dialog work correctly.
To further aggravate the issue sometimes the hex field is hidden completely by the Windows task bar. I reported that issue long ago but it has never been addressed. As you can see in the attached screen shot the color dialog is ALWAYS either over or under the task bar unless the property is one that doesn’t allow gradients.
