Cutter: MH 871-MK2 ,purchased Sept 2013, using SCALP, on Win XP, via USB. no issues until recently. when i turn on the cutter it really bogs down my pc. mouse barely responds, but if i turn it off everything goes back to normal. not a major prob, just incredibly frustrating. any help appreciated. thanx
