It didn't have anything to do with the focus adapter last time either, but that is ground we've already covered. I turned it around "quickly", because I didn't wait for Glenn to return to re-build it. When I found him out of town, I picked up a sled from another source and rebuilt it last week. I used it EVERY day for a week, with burns up to 90 seconds long and it worked fine. Yet within 10 minutes of you receiving it, it is broke again. There is something else in your environment (or your actions) causing the problem. Repairing it again will not be as easy and will not be free again. As you needed, I glued it all together this time. As I warned you, opening it is going to be more trouble now and may cause more damage. If you are sure that your battery is charged well, my only other idea would be the clicky switch.
