In the Sculpt Room => Surface Mode I can't access some tools from the Tool Palette whose section headers are collapsed and can not be expanded. Background: There was a discussion on one of the forums started by Carlosan about the Left Tool Panel using tabs and I suggested: You can already collapse/expand tools under a tool heading section by clicking the triangle to the left of the heading. Perhaps right clicking the triangle would expand the current section of tools, but collapse all the other sections? which I still think is a good idea. I later went back to Voxel mode with some of these Surface Section Headers (LC and Objects) still collapsed. I exited 3D-Coat several times, and it also crashed a couple of times while doing some internal rendering for output. That was yesterday. Today when I returned to Surface mode of the Sculpt Room these sections are still collapsed and will no longer expand. The little triangle to the left of the Section Header changes from pointing down to pointing to the right when I click on them, and the other section collapse and expand as normal, but it will not expand the LC and Objects sections. In addition, bringing up the Quick Access Tools with the Space bar shows all the tool sections that are expanded but only shows the Headers and not the tools of the LC and Objects Sections that are collapsed, so I can't access these tools that way. So far I tried un-installing and re-installing with no success. I also looked through some of the XML files and the system registry to see if something jumped out at me, but nothing obvious did, although I suspect the problem is in an XML configuration file. This is in Version: 4.1.17 all editions, and it also happens with the stable release. Thanks for your help with this...
