that's weird i think it's a problem with my laptop cuz with my home pc (which i rarely use) it works. Probably a problem with my firefox, I heard IE might be the ebst browser for this wedbsite. any truth to that??

this "bug" is still happening to me regardless of whether or not I'm on my laptop. It's just a nuissance.

It is probably another issue with the edit display, where posts that have lots of HTML and/or have been edited many times greatly inflate the page size or break the rendering. These issues are being worked on for the next update.

For future reference, if you have any issue with the forums, please make a new post in the Forum Issues category so the webdevs will see it.

Er, actually that was mostly at Gmooni's unrelated issue here. The little arrow icon doesn't seem to actually go to the last post; if a thread has multiple pages, the best thing to do for now is to just hit the "Last" link in the pagination links below the title in the listings.

No, the edit history cannot be deleted (that would defeat the point), however your issue should already be resolved with the new forum build that went up this morning. Histories are now only loaded when you click the button, rather than with the initial pageload.
