chrisant, I have version 16.0.3 but without any hotfixes. I am glad that there's a fix for this.
Another feature request, very minor: when people add files to a project using a wildcard, they typically want to add several filespecs. For example, I may want to add *.cpp, *.h, and *.hpp files in the same directory. But to do this, I have to either re-navigate to the directory for each one, or to remember to copy the filespec before clicking Ok. The problem is that there's neither a "Clone" action for an existing wildcard entry, nor is it possible to copy the filespec from the Properties window of an existing wildcard entry.
My suggestion is to either add a "Clone" button that'd open a new Add Wildcard window with the filespec pre-filled but editable, OR (easier) change the Properties window to make the Filespec field selectable (while still read-only, if you must).
