Bolt is currently not supported in the Style or for Blackberry 6 as of yet. I have the same issues as you and i uninstalled bolt. hopefully there will be a fix soon for it.
I had same problem. But If you press the "sym" key next to space bar it opens a new screen that allows you to type normally. After you finish typing for that specific field hit "Blackberry" key and then choose OK. It also gives you the option to SUBMIT which is like pressing the Enter key. I hope this helps...
