Citavi 6.8 crashes when opening a project
I just upgraded to Citavi 6.8. Similar to other users Citavi started to crash when opening any JumpToLastPositionAfterActionExecutionAddonproject. I noted that you have advised other users to deactivate the "PDFThumbnailAddon" addon. I do not have that addon, just "JumpToLastPositionAfterActionExecutionAddon". When I deactivated it, Citavi 6.8 started to work normally.
It seems that there is a general issue with how Citavi 6.8 handles addons. Could you look at it as the addons provide very useful features.
Thank you in advance
