Yes, s##t happens.
The plastic sheet indeed shrinks AFTER it expands because of heat caused by direct sunlight or stage lights.
When the instrument goes back into a flightcase directly after a gig and into much cooler freighthold (truck/plane),- the plastic sheet shrinks.

Hi everyone, It's been a while…

?

Thanks to your suggestions, I fixed the sticking buttons on my (US) Xpander by filing the edges of the button holes to make them a bit wider.? (In fact, the holes look nicer now that they don't have ages of crud stuck to the sides. :P)

?

I believe that the original cause of the sticky buttons is that the thick plastic sheet covering the front panel shrinks over time.? As the plastic shrinks evenly, it tightens towards the center of the panel.? On my Xpander,? _every_ button hole was shifted towards the center by a few millimeters, making the holes tighter against the sides of the buttons that face away from the center.? To re-widen the holes, it only takes a bit of filing the plastic cover where it had intruded on the hole.
