What a cool upgrade - version 5.2 - many thanks for all the work that went into it. i am an enthusiastic user of the offline-version (HTML-only) of TW for my personal note keeping and I try to keep it as pure as possible. Despite my engineering background I would like not to bother with any technical details here. Therefore I was looking for a "foolproof" upgrade hint (like for other software). There is - but I had to google for it. No link included in the extensive documentation here
