This subject has been raised over and over on the forums here. It doesn't come from IS but from Jamba strobing. I prefer to have strobing because it keeps my guys always facing the same direction which is really important in PvP specially arenas. My PvE setups I set it up without strobe. I think it happens when the Master (main) switches because frequently I see that the display team option of show on master only doesn't activate on main window but continue on a slave. When I go to Jamba it also show that my current main isn't the current Master, so there's a problem.
The worst part is that it happens sometimes but most of the time it doesn't and I cannot really replicate the (supposed) bug.
I saw Ualaa mentioning in some other post that one possible fix is to put strobe +3s. I'll try that.

But meanwhile, does anyone have another solution? Would it be possible to somehow create a strobe in IS?
I guess you could do some sort of /follow (not sure what kind of command would do it though) as one step of all or some (the needed ones) keymaps but that wouldn't solve situations when you just use mouse to move.

Another question, is it essential to have strobe follow when playiçng melee teams? Or IWT is enough?

Forgot to mention that it happens in both versions of Jamba.

Thank you all in advance.
