RefMan12 and Word 2003 don't work keyboard shortcuts

With Ref Man 12 the keyboard shortcuts don’t work in Msword 2003 (I press the combination keys and nothing happens) I try to change the combinatios keys too but nothing happens.

I could solve partially this problem (I choose in Word 2003 Tools/personalice/KeyboardShortcuts, I look for Macros and select the macros of CWYW and asign a keyboard combination…). now it works, but it is not a “clean” method (It would be better if the keyboard shortcuts could be assigned in the CWYW plugin preferences)…In fact,  the plugin still have the bug  (I have not solved it, only bypassed)
