Did you read my reply? It's very time consuming to investigate 100 lines of code with multiple issues. Can you post code that shows each problem _seperately_ and excludes anything that's irrelevant? Like fonts, say. If you can't duplicate the problems seperately in simple examples, then you might start from one of the simple examples and incrementally add in the other features--one at a time. That should help you pinpoint the cause(s).

Otherwise, hopefully someone else reading the thread will have the time or eagle eye to pinpoint the problems.
