Windows come open on the road after lubing openers

[Airwave503]

The window openers on my '61 Safari were sticky when I got it, so I hit them with some WD-40 and got them lubed up so the open and close really easy. So easy that when I am towing, they jiggle open and the window start flapping up and down on the freeway.

These are the latch handles: Hehr Window Lock

Anybody run into this and find a way to address it?

Thanks!

I had the same problem with my '63, it went away after I replaced the window gaskets, they gave it some squeeze so the latches didn't wiggle open
