Pierre, on several occassions now -- circumstances I can only describe in the most gen'l way -- equations stop working, keys stop functioning, weird stuff happens.
A program re-start fixes it but still.
Example: I have an equaiton (that you helped me with) that turns font a different color when item is marked done/completed
Yesterday, it stopped working in the middle of the day for no apparent reason
I've had <shft><enter> stop working as well as <ctrl>+M
Yesterday, again, I had a number of sub-items disappear from view causing me some heart palpitations
Again, I restarted IQ & everything returned to normal
It's very weird & very disconcerting.
I know I'm not giving you much to work with here but the only thing I can say is it seems to happen if IQ is running for a long time, i.e.
