ROM sent keys twice at once

why does isboxer sent double keystrokes at once .... it does from a-z 1-0 also with shift and ctrl. ive checked in my keymap and notting seem to be wrong or if i missing anything?
here are what ive tryed:

Win7 64 Boing with 1 PC
reinstall + updated inner space & isboxer V1.11 Build 5469
file > Clear in Isboxer and made a new charecter set from wizards and just use the default keymaps and all that(not fix the problem)
redo all my game profile In Inner space > configuration (not fix the problem)

so far thats all ive tryed and notting seem to fix the problem.

There may still be a bug with Runes of Magic receiving double keystrokes. I will try to check this out today

Inner Space build 5470 should correct this issue with Runes of Magic, this is currently the development build of Inner Space. To try it out, right click IS, select Patcher, check "Download development (test) patches" and then close and restart Inner Space

reinstall to Build 5430 and works like a charm aswell TY for look it up lax
