> version 4, which you can still find in the Guide subfolder "Variable") and last,
> but not least, the newest GCVS.

> If the newest GVSC (= ".tdf") is installed, Guide crashes when one is clicking -

> - second, right-clicking this symbol to obtain more information.

> I had already seen, while making my own ".tdf"s, that some Guide users had not
> given any ending to their ".dat" files, containing the catalogue. (The .tdf
> system requires two files, the "catalogue = database" and the "tdf file
> accessing the catalogue). So to be sure, I completely reinstalled Guide 9.1 (I
> had a backup copy with my additional files in it which i simply copied over) and
> waited to the very end of the installation before putting in the NEW GCVS files
> (tdf system). While Guide did deliver correctly the information from the OLD
> GCVS catalogue until this moment, it did crash after having put in the NEW GCVS.

> So ist is clearly the catalogue itself, which is the culprit.

> Remembering that I had seen user data sets (.tdf) without having the ".dat"
> ending, I simply removed the ".dat" ending (including the point) from the NEW
> "gcvs_cat.dat" file ... and Guide didn't crash anymore. To make it perfectly
> work (otherwie you would not get the information from the new catalogue "in
> parallel", it is however further necessary to also change the reference in the
> first line INSIDE the corresponding .tdf file (= gcvs.tdf), by opening this
> second file with notepad and deleting the ending). Now you can alternatively
> have the information from the old GCVS catalogue and from the new one by
> clicking on the corresponding star symbol (at least in my case = freshly
> installed Guide 9.1).
