Why is it that if the bot click on the skills tab i go from 30+ fps to 2-5 fps?

What version are you on?

on version 1.3.3 is drops fps from 50 to 2-5 when I open music tab ^^

What about version 1.3.4? I know about this issue, but I can't remember in what version I fixed it.

Yes 1.3.4 s the one that's lagging when I click on the skills tab

This should be posted in bugs, w.e. I guess, and is this during script running or just in general? Never happened to me either way.

happned if you are running a script and if your just using the client without a script

This is a bottleneck resulting from the client having to copy a lot of interface position data (the skills tab has a lot of childs iirc). There are work around for it, for example making data copies based on demand. We will play around with it soon, but I'm not going to put this on top of our priority list as of now as it seems that this is an issue which doesn't result in much problems so far.
