[TxMt] Disabale reloading of sidebar contents

[N. Binder]

Hi all,

I remember that there was a way to disable reloading of the directory  
contents of the sidebar (which causes timeouts of several seconds when  
switching focus back to TM). I googled, looked in the wiki and the  
blog, but couldn't find the post about it any more :-(

Does anybody know how to do it? Should be a quick answer.

Thank you for your help,
Nick
