I have been using 4.2 for a long while and recently tried upgrading to 4.3pre9. In 4.2 the order of buffertabs seems to be based on the global options "Sort buffer list" and "Sort buffer list by file name", both of which I normally check. Doing so in 4.2 causes the buffer tabs to be sorted by filename and stay in that order. With 4.3 the order seems sorta by filename but each time I select a tab it jumps to the front. This causes the other tabs to get out of order until finally each tab selection creates a new random ordering with the most recent buffers in the front row. I find this to be almost unusable - I spend too much time searching through the tabs every time I want to select a file.

I have tried the two 'sort buffer list' checkboxes in various combinations - they seem to have no effect whatever.

I am running mainly under WinXP but also Ubuntu and Red Hat.

1. Is this the correct behavior? Has the behavior changed from 4.2 to 4.3?
2. Is there a fix? Is this a bug?
3. Should I report/post to a better place than this forum?

Thank you very much for any clues provided!
