What version macroworks are you running on new computer? What version were you running on old computer? And did you just copy and paste your old .mws file over? I switched all my x-keys to new computers and when I did, I downloaded and used the new macroworks program, then copy/pasted all my new comps with the old .mws files instead of reprogramming each comp (or one and copy/paste). Some buttons worked fine, some worked strangely, some didn't work at all. Was more trouble to reprogram a new layout, so I went back to the old macroworks....version 1.0.0.0 and now everything works fine
