I've recently purchased the Frost keyboard and was thinking about swapping out the spacebar MX1A-C1NW tactile switch for a linear switch (MX1A-11NW or MX1A-21NW). I typically rest my thumb on the leftmost edge of the spacebar and I've noticed that when I push down, the spacebar would sometimes get stuck on the tactile groove due to the weight of my thumb resting on the spacebar. My thumb is similar to a crocodile's jaw in the respect that the muscles are weak lifting up. I was wondering if there has been anyone else having similar problems, who could offer some input. Thanks.
