It changes the behaviour of my testcase, yes, but it doesn't cure the problem. When swap_token_timeout is the default 300 the screen freezes are longer in duration, about 30 seconds. With a swap_token_timeout of 0, max screen freezeis about 10 seconds, inter-foliated with freezes of less length. On a positive note, the _total_ time of "unstability" is equal in both cases. Wh ich in my animation test means 6 minutes. I said 3 previously, but that was wrong. Didn't let it run long enough. Cheers, Mats Johannesson
