After a hectic New Years my treasured GRD as developed a slight problem. The four directional buttons and the menu/ok button have become misalligned or sticky, forcing me to push them a little extra hard to get them to function(similar to cracking your knuckles..) Has any had this problem aswell, is this something that will work itself out or would unscrewing the casing be a bad idea to see what is going on. There seems to be an outward buldge by the left button/screen edge but it seems to be part of the design. It hasn't been near any sand/grit etc. It's probably from crushing and stuffing into a bag or my pocket. Any ideas about what i can do to fix the problem, everything is working fine otherwise. thanks for any tips.
