Problems with the Thunderbird Extension Mailbox Alert 0.9
The Tunderbird extension Mailbox Alert seems to be really useful. I think: It internally adds a folderListener and and let the user define an external program, that is called every time the number of unread messages has increased. At the moment Mailbox alert does not allow to define actions for virtual folders. But I fear there are other problems, too:
When “Mailbox Alert” is installed and activated I get a message-box containing the following text:
Warnung: Nicht antwortendes Skript
Ein Skript auf dieser Seite ist eventuell beschädigt oder es antwortet nicht mehr. Sie können das Skript jetzt stoppen oder fortsetzen, um zu sehen, ob das Skript fertig wird.
Here is the translation:
Warning: Script unresponsive
A script on this page may be busy, or it may have stopped responding. You can stop the script now or you can continue to see if the script will repeat.
The process of fetching the mails from my pop-servers and moving them to the right folders using the thunderbird filter-rules slows down dramatically.
I observed the described behaviour on a high-end dual-core PC running the german version of Windows XP and Thunderbird 1.5.0.5. For testing I disabled all other Thunderbird extensions I use. The dom.max_script_run_time was set to its default value 5.

Using the english build of Thunderbird 1.5.0.5 I notice the same thing. When I get the script warnings mu CPU usage on one processor jumps to 100%.
This is on an dual Athlon 2600+ PC running Fedora Core linux.

Thank you Greg. I wrote a mail to Jelte Jansen, telling him that this problem seems to affect (the growing number of) dual-core-systems particularly.
