This release solves the parsing of keywords and #x,#b,#o, #c literals in assignments. Support was added to parse make-pathname expressions. The ctrl-i and ctrl-t shortcuts were improved. The default help browser for Windows was changed to IE and support for Firefox was added. A bug with checked menu items has been solved. You can close now a interaction buffer via its popup menu. Some focus management problems were solved (one could cause a serious hangup). The load editor content and compile editor content will now ensure that the cursor is at the beginning of a new line after the operation.
