1st time it happened : I've created a new form, renamed it and saved it. Worked 3-4 hours on it and saving work in progress from time to time....

Closing the IDE and running it again... Loading my project, trying to compile it but IDE failed with "unknown error" exception (catch with madexcept). Previously saved form (pas + dfm) was missing... I only see trace of them on the _history folder.... (see missing dfm.~6~) :

fmReglage.dfm.~1~
fmReglage.dfm.~2~
fmReglage.dfm.~3~
fmReglage.dfm.~4~
fmReglage.dfm.~5~
fmReglage.pas.~1~
fmReglage.pas.~2~
fmReglage.pas.~3~
fmReglage.pas.~4~
fmReglage.pas.~5~
fmReglage.pas.~6~
