Hi,

I found a (not the) solution (it’s a probably workaround) to avoid that Guide crashes when you click on a variable star, like R or RR And, (...thank you Bernd and Roger, your thoughts and problems gave me the idea to search and directed into the right direction) and then on «More information».

This pre-supposes that the new CGSV (current, from Cds) in «User data sets» ist set to «On».

 (If is it set to «off» Guide will certainly find the star (with all means of searching, i.e. through the Menu «Find/Object name», through «Find/Star/Variable», through «Find/User Data Sets» or a toolbar shortcut, but ... you wont’t see the designation of the variable star on the screen and get no specific information on the variable star, if you rightclick on the star symbol, because the information will come from another catalogue (like UCAC).

But if you have the CGSV put to «ON» you will get alle the variable star information through the new catalogue, ... and Guide will not crash anymore if you try to get that information, ... and if you are on the "wrong" star symbol from the «wrong» catalogue («zoom in» fully to see that there is a star symbol for each catalogue, leading up to 4 symbols in some cases).

So here is the trick: Just remove (don’t delete, keep it somewhere else !) the files «LG_TYCHO.LMP» and «SM_TYCHO.LMP» from the Guide subfolder named «HIPP» (Hipparchos). Even if in the «Hipparchos» folder, these files seem to refer to the TYCHO catalogue. .... And I can’t find any trace of the TYCHO catalogue in my Guide folder. ... So it is perhaps a dead reference, and perhaps (I have no clue) the reason why Guide crashes, when it is searching for «More information» based somehow on the old catalogue ???

Sofar J haven't seen any negative side effect from removing these files, but some people are perhaps working with the TYCHO catalogue ??

And don't forget to put the CGSV user data set to «ON».

Clear skies
