I'm getting the "deadline expired" message. I opened two instances of Sigil and opened a different epub in each of those instances.
Interestingly... I'm getting a new warning message about Sigil not being able to find any webengine spellcheck dictionaries (not that we use them in Sigil).
Code:
Warning: The following paths were searched for Qt WebEngine dictionaries:
C:/Program Files/Sigil\qtwebengine_dictionaries
C:/Program Files/Sigil\qtwebengine_dictionaries
but could not find it.
You may override the default search path by using QTWEBENGINE_DICTIONARIES_PATH environment variable.
Spellchecking can not be enabled.
Seems harmless enough, but has something changed in our profile for WebEngine to cause that? Or is it because of the switch to a memory cache instead of a disk one?
EDIT: I can see where you explicitly set setSpellCheckEnabled to false in the default profile in your commit, so something else must be going on.
