Same problem I had. Disabled Swype and installed the beta version from their site. Allows for theme change as well as correcting the problem you are having.
I Don'tKnow If There Are Any Other key Biards Installed....Love Swype Though.....I Guess I CouldLearnTo Push Every Key Again.But Then It StillCapitalized Every Word...WillLook For Other Installed Key Boards
Try deleting cache on swype. Open up settings->applications->ALL-> scroll down 'till you see swype, then clear cache/data. See if that fixes your issues... if it doesn't I suggest, purchasing the Swype Beta for .99 cents that I linked on my previous post.
