Version 1.17 is available for download.

This update fixes instability issues caused by an intermittent behavior of the MobileMe service, which has worsened lately and started causing frequent failures. While implementing workaround for that issue I found a way to make the plug-in tolerant to users logging in and out of the MobileMe web service while using the plug-in. Now you can access your mail and browse your galleries while the plug-in is uploading pictures.

Another addition, is the ability to submit debug logs for troubleshooting right from the plug-in. The Submit Debug Log button can be found on the Plug-in Info panel.

NOTE: Version 1.17 is not going to resolve the issue with Lightroom 3.0 for Mac (x64). For details, see the plug-in's home page.
