Hmmm.  A previous reply to this thread by bbb_uk has now disappeared.  I will take it that this is the result of faulty forum software since if there was any post which it made sense to delete from a forum management point of view it was my original post.

After doing some tests based on the now deleted response from bbb_UK in this thread I can confirm that problems with this forum stalling when entering the site at www.saynoto0870.com or when clicking on any links in emails from the forum notifying new posts is caused by clearing Internet Explorer's cache of temporary internet files.  I do find this rather hard to understand as with any other web forum I belong to it would only be clearing out all cookies that would create such an issue, so there is clearly something odd about YaBB V2.1 and its operation.

The relevant item is in the Tools/Internet Options/Advanced menue of IE6 and is the tick box option saying "Empty Temporary Internet Files folder when browser is closed".  I imagine that this has the same effect on an automated basis as the manual "Delete Files" button available under Tools/Internet Options.  But having the advanced menu option ticked as well simply runs this facility every time one exits the IE6 browser.

As a person with a large amount of antispyware and antvirus utilities running I naturally though that setting this option to on was the prudent thing to run and none of the other web forums I visit have exhibited any probelms as a result of this.  However it does seem that YaBB V2.1 relies on saving information in the Temporary Internet Files which it looks up the next time you start IE6 and visit the site.  Although this is clearly very bad practice (temporary IE6 files may be cleared by the user at any time and doing so should not cause a problem) it is clearly what the YaBB V2.1 developers have done.

I suppose I now have to make a post at www.yabbforums.com and hope they get round to doing something.  In the interim I either have to run on an insecure basis or click the Refresh button about 3 times every time to get taken to a new post in a thread.

Since I so often seem to be a critic of this site these days I just wanted to say well done to Daniel and/or anyone else involved in resolving all the problems that were occurring with the site running so slowly.

The site is now veritably wizzing along and I find I am jumping to threads from links in update emails at lightening speeds.
Well done to all concerned in solving this problem.
