Preventing linseed paint sticking windows shut

[Me!]

Does anybody have any advice on how to stop windows getting stuck shut with linseed paint whilst it is drying please? Even if we get a good summer, it seems to require the windows to be open for weeks to prevent them getting stuck which is not possible for obvious security reasons.
The one window I have successfully done with linseed paint is a modern one that has push-in plastic seals which I was able to remove during painting to leave a gap between the opening casement and the frame whilst it was drying. Even so, when I refitted the seals after many weeks of drying I found I had to dust them with talc to stop them sticking.
The windows I’m now about to paint are all old ones where the side-hung wood casement touches (in some places!) the other wood of the frame. The only thing I can think of doing is to unscrew the catches and temporarily refit them with spacers behind them to create a gap of a few mm. Has anyone got any other ideas please?

Thank you.

How about a thin strip of polythene?

It is a problem of linseed paint. When I've done sashes I've removed the sliding sashes and boarded the window up temporarily - is that an option for you, take the casements out and paint them elsewhere?

Even when putting the sashes back I found they do stick for a bit, but by making sure the windows were opened at least once every day they were OK. I did put some silicone spray on one that kept on sticking - about 2 weeks after it was painted - which doesn't seem to have done any harm.

My trick for reducing the stickiness of just about anything is to rub some talcum powder on it. Obviously the acceptability of this solution depends on the colour of the surface - white talc doesn't look good on a dark background (although when you wipe off the surplus talc what remains is not too starkly white). However, if your linseed paint is white (or a very pale colour) a thin line of it on the most critical sticky edges might not be aesthetically unacceptable.

Thank you. I think all the suggestions will probably be used at some point in the various different locations.

I use various forms of HD wrap depending what is in use in the kitchen at the time.
It will prevent sticking together/separate sticky paint easily without damaging the paint.

I've used it for years with all sorts of paint.
It enables the window to be locked while the paint continues to dry.
