[ReneMiner]

I have an Error- but i have no time to locate the cause. My girlfriend is annoying me to play something...

I loaded the above posted AVL-Tree-example into thinICE- then let it run (f5)
after ending your sample and thereafter try ending thinICE by pressing esc-key i get message of undeclared variable in tControl_Codefield.InputKeyboard line 2471
(bResult) which is a static and declared for sure few lines above (2467)
