I'm on a T-1 running IE6.0.2800 with AdSubtract Pro enabled and up-to-date. Over the past few days I've been getting page load failures on FT, particularly when replying to a thread, but the reply still posts. I have to refresh my session in order to see the FT screen again.

(Edited to add following)
Happened again on above post. Error "Cannot find server or DNS error" screen came up after submitting post. Pressed IE's refresh key. Got FT screen with vBulletin error message: "Invalid thread specified. If you followed a valid link please notify the webmaster."

Restarted FT and found original message above had successfully posted. Reentered this thread to edit this message; thread had still not loaded all the way at 45 seconds then I took a nature break. Came back and edited this message.
