To clear the tools window, hit the “R” (refresh) button above the window.
There is no such thing really as a “base tool”. A tool is essentially a collection of subtools, even if there is just one. Only the selected subtool will be scaled etc.
These icons are used for boolean operations - best to read the manual for this (version 3 I think they came in so look there)
The eye icon has different effects depending on whether the subtool is the active subtool or not.
*Clicking the eye of the active subtool to on will make all subtools visible if they weren’t already. Clicking it to off will make all subtools invisible
*Clicking the eye of an inactive subtool will reveal or hide that subtool, even if the active subtool’s eye icon is off.
Re. your saved project: it could have been caused by several things. One is user error - did you remember to save? Or did you save the tool rather than the project at that stage? Also, ZB doesn’t remember which folders you save into. For example, if you save the project in Folder A, then save a tool in Folder B, next time you save the project it will be in Folder B. Perhaps do a search of your HD to see if your project was saved elsewhere.
