if there are things that make it seem more/less likely that would also be helpful.
the challenge for us here is that we have never seen it happen. not once. there is very likely a triggering mechanism – for example: maybe a feature that a 3rd-party stack uses, or perhaps a specific type of content.
whatever that mechanism is, a few have it, but most (like me) do not.
in order to fix a problem (or help you work around it) i need to understand it. without knowing this key triggering mechanism i’m very much in the dark without any understanding whatsoever.
what would be helpful: the next time you experience this problem take your hands off the keyboard and mouse. stop. think. what was the very last thing you did. is anything unique about this document or this page? have you been using RapidWeaver for a long time? is the document very big? is the page very complex or very simple? is there a particular 3rd party stack involved? did you recently add/remove something? did you recently publish the document? open? save? or recently switch pages?
most of these details, of course, are probably unrelated – however if each person that experienced this sent me their details (yes, it’s always more helpful to send direct to me rather than posting here, thx!) then there might be a common thread that could be found and used to track down such an elusive bug.
