I've been using Mechjeb for quite sometime and appreciate all the work that goes into it. But, I've run into a problem using it since the last KSP update (Steam x64 and x86 versions)- when I launch using it, I lose *all* keyboard functionality- manually jettisoning stages, manual RCS and rotation- and it'll indicate that I'm under thrust when circularizing and I'm not. I've removed and reinstalled it, but it continues to lock out. This includes new and presaved rockets Mods I'm running- KAS Kethane Firesplitter Module Manager CLS Toolbar Ship Manifest Magic Smoke Industries Extraplanetary launchpads
