palette panel is not deactivated

[Geppetto Luis]

Since I installed cc2018 I'm having a problem with the palette windows

if I start the palette panel with a html panel button

even if I close the palette panel and then click on an area outside photoshop

and then back in photoshop this reappears

as I could solve this problem.

The palette window?  There are many palettes in Photoshop.  Is the palette window  you have a problem with a palette installed by some Photoshop extension you have installed? What you show looks like that may be the cast and the Extension is have a problem with CC 2018.    Check with the extension developer see if they have a version that works with CC 2018. Make sure you tell them your using a Mac.

I tried the same extension on cc2014 and it works perfectly

maybe the problem is cc2018?

Have you ask the developer if they have a version tat work in CC 2018.  There have been many System and Photoshop changes since CC 2014 and CC 2018 has at least three updates.   Compatibility problem between version of Photoshop is not uncommon.

I contacted the developer

he told me that it is compatible with photoshop cc2018

The problem creates it only with the palette panels

with the dialog panels it does not do this problem.

Who programmed the problem palette Adobe or the Extension developer? The developer may have a problem with how the  implemented Palette works in CC 2018. Some  Adobe interfaces may have been changed  the extension developer may need to make a changed for CC 2018 you state it works in CC 204.
