Lag and please fix it

i went to skin editer but it lagged me

hello, yes, may you please tell me what browser you are using, and have you tried updating Flash and Java?

It also lags whenever you have some other programs open. Skype and Spotify are fine, but anything else makes it lag.

as said make sure your programs are up to date, i will make sure that saviski searches for faulty code, which can cause lag
