I have no problems with anything in v1.3.9h when using PHP 5.2.12 or newer versions.
That includes ALL the symptoms discussed in the previous 50 posts of this thread. ie: more specifically, I DO NOT HAVE any of those symptoms when using PHP 5.2.12 or newer (including up to 5.3.3).

However, I've confirmed that PHP 4.4 does indeed dislike these changes made in 1.3.9h.
We're working on an update that will fix that incompatibility.
