Since I do not have a wat myself to reproduce the error, I cannot do much more. The only idea I have is that the deletion is done during the event handling of the LyX text canvas and, since it deletes the inset's form, a crash occurs when xforms tries to send events to a non existing form (maybe some linked list has not been kept up to date). Ideas anyone? It seems that many people have been bitten by this one. JMarc PS: Frank, on what system is that? PPS: I replaced lyx-users with lyx-devel, since this is where help should come from...
