When installing the TAdvStringGrid source package the shortcut to the Developers Guide is broken. It refers to "...\Documents\tmssoftware\TMS TAdvStringGrid\Doc\advgriddevguide\TMS TAdvStringGrid v6.0 Developers Guide.pdf", but should refer to "...\Documents\tmssoftware\TMS TAdvStringGrid\Doc\TMS TAdvStringGrid Developers Guide.pdf".
Thanks for reporting. We fixed this. The next build will address this.
