I wonder if humid weather causes proseal to be sticker?
Think "tacky" not really "sticky". That canopy front skin is thin, it doesn't take much to hold it in place while the act of raising the canopy shoves it into proseal that shouldn't be there
It only takes a fraction of a second to happen and, after opening it a hundred times without issue, you don't really feel the need to baby it.
Once the canopy forward edge comes in contact with the proseal, any upward movement applies forward pressure and keeps it in place and it will start bending until you get the dreaded "pop".
It's probably only ever going to be an issue on the top middle where the canopy skin is easily bendable.
