Re: Crash in NSControl's sizeToFit

You're not allowed to do *anything* on non-main threads unless the documentation *explicitly* says that it's OK. You should approach this subject with great caution and restraint. If you can't prove that something is safe, assume that it's not, and stay away from it. j o a r On 1 feb 2010, at
