I gotten the same problem. I am using the new windower, not sure if that may be what is causing this issue.
I read someone had luck reinstalling XU, so I did that, and also reinstalled CTS 1.2.2
But the error still persists. The Map plugin, and the Fishers works perfectly, its only CTS that has an issue. I am not sure why.
[Edit]
I attached the log, and it seems to be this error causing it
[2005-08-07 14:43:31] Entering main loop...
[2005-08-07 14:43:43] Dark Crystal
[2005-08-07 14:43:43] Nebimonite,1,Win. Tea Leaves,2,Distilled Water,1
[2005-08-07 14:43:49] Failed to find ingredient slot!
It quits with that error after it selects the Nebimonites, and then tries to select the number of the item to use.
(!empty($user->lang['QUOTE'])) ? $user->lang['QUOTE'] : ucwords(strtolower(str_replace('_', ' ', 'QUOTE'))):
The log tells gives me the error "Failed to open inventory!", "Failed to open ingredient selection window!" or "Failed to find ingredient slot!", what can I do?
This is most likelly keyboard related, try the following, from less severe to most sever:
Enable compact keyboard mode, see above how.
Make sure you have decent frame rate in FFXI.
Close down all background applications, especially p2p programs and web browsers that might be stealing cpu time.
Close down FFXI, close down XUnleashed and start it all up again.
Restart your computer.
Make sure you're using an American English keyboard layout.
Get a new american english keyboard.
Why all this trouble to navigate menues? Well it seems XUnleashed sends scan codes to press keys, this means if your keyboard looks different than the one Admin uses then his code doesn't work anymore.
All of these I have tried as well.
