There is a problem with vRewrite when using it with the "redirect threads" option enabled. If you try to change thread modes it will not let you because the redirected URL does not include the "mode" variable. After hacking several plugins to no avail, I discovered that the plugin attached to the "global_complete" hook is incorrectly rewriting the links and removing the "mode" variable. After further study, I discovered that the problem was not happening on the "hybrid" mode link, but it was happening on the "linear" and "threaded" mode links. If you rearrange the order of the variables in the SHOWTHREAD template, it stops vRewrite from rewriting those links improperly. You simply need to make this small change to your SHOWTHREAD template:

This is sort of a hack for something that really needs to be fixed in the "vRewrite - main script" plugin attached to the "global_complete" hook, but that plugin is so ugly I can't figure out where to fix it.
EDIT: After further study, it appears that you also need to modify your "VRewrite - redirect handling" plugin (attached to the global_start hook). Simply replace it with this edited code to keep the redirect script from destroying the "mode" variable.
