Sorry for the delay. We have tried several things, including updating to the latest dll's you have available. On some of our test Mac's, the uploader will actually get through the upload process, but the browser window is frozen during the upload, and remains frozen once the upload is complete. This happens on your test site as well (http://ajaxuploader.com/demo/Large-File-Upload.aspx?UploaderDebug=1). We tried to capture the debug window, but we can't get all of the debug messages there because the window is frozen, so we cannot copy the text. Even a screenshot is not possible because we cannot make the debug window larger to capture all of the messages.

Is there a way to make the debug window sizeable so we can capture a screenshot of the window when it freezes and that that to you?

Thanks,
