tiny fedup with crashes…

hello

i use TeXmacs (since years and years) hours each day,, opening ~20-30-40-50… diffférent TeXmacs documents every day, sometimes several .tm opened at the same time in differnet macos’ spaces…
all is totally right, excepted that TeXmacs crashes~1 or 2 times a day
and it crashes everytime after the same opération :
Cmd-Shit-R
that is : Document->Actualiser->Le Tout
in english something like Document->Actualise->All… ?

when i press this combination of key (essentially to update the summary)
i am obliged to take the precaution to have all thos folders opened behind the .tm documents in case it crashes : to reopen them and go on working

what happen when it crashes : the TeXmacs windows stay fixed, no possibiity to edit the document, not either to edit any other TeXmacs opened document ; the « lift » moves without any effect on the text

i can not predict when it will crash or not
i was thinking it might crash for old documents
but juste one minute ago it has crashed this way with a very recent document

am i the only one to experience this ?
