Hi,

Thank you for this quick reply.

In theory, all drawing code is called from "performSelectorInMainThread" calls. Furthermore, this problem only occurs on a very restricted number of computers, and seems always reproductiple on these computers.

However, who knows, i may have forgotten a very rare case. I'll check this.

Thanks,

Vincent

Hi Vincent,

Firstly Cocoa drawing code is not thread - safe. If possible better to remove it run from the different thread. If you requires, have a look at NSApplication's + (void) detachDrawingThread:(SEL)selector toTarget:(id)target withObject: (id)argument class method.

- Apparao.

Hello,

A customer have a strange crash when using my application. In fact, this is not always the same crash, but it's always a crash on some locking function, in cocoa drawing code.

His problem is not reproducible on the mac i could access.

There is no input managers, or similar add ons installed.

Does anybody have an idea of the cause of the problem?

Here is some samples of crash:
