Terrain builder objects moving by themselves

[-DL- Shane-uk 18]

Hello All 

 

so i have started to play around with terrain builder working on a good size terrain but seem to have an issue when placing objects 

 

when in Buldozer i can select an object and move it then move to the next one only to see the object i have just place move by itself a few times 

 

i did wonder if it was a memory issue  or CPU issue  as its like its freezing or something but i have an i7 CPU and 32 GB of ram so the pc should be able to handle it 

 

This wouldnt be a problem if i was placing trees but is an issue when placing walls and buildings 

 

does anyone have any ideas that can help me ?

i got this sorted in the end  i started terrain builder from its own shortcut as admin and it runs fine now rather than running it from arma tools
