Bc2000 (for the BCF2000 & BCR2000)

hi again, 

im beginning to make progress with my bcr2000. configuring direct 
form the bcr is actually quite easy, now i understand the 
instructions in the manual (im a complete midi noob). i at last setup 
cc's on every knob/button and hav almost made a worthy preset for 
live. except one majorish issue. i want to use buttons to launch 
clips. 

button 1 is say set at cc# 60, toggle off, on parameter = 127, off = 
0, ch 1 

when i map the button to a clip and then come out of midi map mode, 
the clip is constantly re-launching without me even pressing any 
buttons. in fact the only way to stop the clip is to go back into 
midi map mode. 

so then i change it to toggle on, still get the same issue, also if i 
change the on/off parameters, it still happens. 

everything else seems thing. 

i can toggle mutes, solo's, etc. and also select tracks and toggling 
on/off works fine for other functions other than launching clips. i.e 
i have toggle off for beat repeat, so i can hold it down like note 
repeat function on an mpc. pretty good. 

any ideas what im doing wrong when mapping clips? 

thanks
