I am not on Windows so someone else ill have to confirm that is not the way it normally works and perhaps you want to reset your settings they seem that they might be corrupt.
I triend restoring default everything by holding ctr+alt+shift at start up. Afterwards the problem is the same
I promise you it doesnt normally work that way because it makes the program inoperable...
Preferences > Interface > Uncheck Auto-Collapse Icon Panels
As Scott said, normal behavior and "as designed". If you want to stop it, check the respective options. An alternative would be to simply create your own palettes and stack them neatly. Then they will only collapse/ roll up when clicking on the respective title bar.
That preference was already unchecked.
I'll try to be as precise as I can with my words.
Look at the attached pictures in my first post. The gradient window works fine. It stays up forever. But if I click on one of the color sliders, so I can select a new color, then the mini-menu that lets you click on what color you want closes immediately. As soon as I click it, it just closes, maybe in 1/2 sec or a little less.
The gradient window is fine...but choosing a color doesn't work well...the color mini-menu closes.
Is that what you thought I was saying originally?
I'm having the exact same problem and I can't find an answer anywhere.
