Hi Rikki,
No it doesn't have anything to do with moving it. One of the guys having the problem has never moved his. I'm very careful with mine. It seems that only a very few of them are having the problem. I think I've heard of three or four out of the thousands sold. I'm just one of the lucky ones!
I haven't taken the time to get my into the shop yet, but will pretty soon.
I certainly wouldn't let it deter me from buying one.
Go for it!
what has to be done to fix this problem? if it is a problem?..
design flaw, cheap locking mechanism, or what?....as long as it stays up and you can adjust angle should be a problem while playing right?... up or down thats it..nothing is perfect
