I´ve figured out that Flare is extremly slowly. First I thought that the whole program is affected, but fortunatelly only individual topics are affected.
In these topics are nested invisble tables.
Example:
I often use invisible tables, e.g. for precondition and condition blocks at the beginning and the end of a task topic, dita style, I love it
Now if you put another invisible table in this first invisible table, e.g. by converting to text a safety note snippet or a note with symbol snippet
two invisible tables are nested. Sometimes in the nested tables are images as well.
Do you have the same problem? In my case the mouse is frozen and Flare needs a lot of time to check my topic
