XPrealWX blocks letters "L" and "B"

Hi,

Whenever I try to enter the letter "L" into my FMC or any other dialog within X-Plane, I only get a popup with the XPrealWX status bar. Same for "B", exept for the popup. All other Letters/Numbers work fine. Looks like the plugin catches these inputs before they can be passed through.
I've not found a setting, where those key assignments could be changed, so the only workaround at the moment is to temorarily disable XPrealWX while writing.

Greetings,
Michael
