What version of photoshop and operating system are you using?
Could you explain what you mean by close tab groups?
Adobe Photoshop Version: 14.1.2 (14.1.2 20130923.r.427
Operating System: Windows 7 64-bit
Once you open any of the Adjustments from the adjustment panel, eg
levels, color balance. To get rid of that adjustment you use the upper
right pull down and click on close tab group to get rid of that
Hi tjbinno, I've moved this thread to the Photoshop General board where you might be able to get more help.
