It sounds like your code has some serious memory leaks. The easiest way to look at the memory usage of your app is with the Activity Monitor app. Or if you’re more comfortable in a shell, use top. The most significant statistic to look at is RPRVT. I took a brief glance at your code, and it definitely looks like you’re not cleaning up everything you need to. I’m not very familiar with the CoreGraphics API, but you call CGWindowListCreateImage and then never seem to dispose/release/free that image. Considering that the image ref must be holding onto a giant pixmap the size of the screen, that’s probably the source of your problem. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
