Hi
I don't understand what you meant about not seeing a place to post to the forum, yet you posted to the forum, so please clarify. I'd like to help but this confusing.
As for the error I have make a test post and have since removed it (as a regular user) and was not able to replicate the problem. If it's to do with your browser being a bit odd then there is little chance I can do anything about that.
Have you managed to replicate the problem?
On the Milkytracker topic, you might be better off posting inside the Milkytracker subforums. However, in the Tracking forums of The MOD Archive there are several threads concerning sample sources.
