OK, blueblaze's problem is identified and fixed. But swedge, I still have no idea what's going on with the key thing. If it keeps happening, can you give more detail? (does it appear in a dialog box, what does it do afterwards, etc).
It may be that the JavaScript error that was causing blueblaze's woes caused Firefox to spaz out and have dysfunctions, but I have 1.0PR and I haven't noticed it, so I dunno.
