bobcad v26 simulation jumps in spots

when i run a simulation in certain spots the simulation of the tool actually jumps to the next segment of code...running sim in time based mode. This usually happens on straight sections. If i switch to length based mode then it seems to simulate fine...and looking at the lines of code it seems to look ok....its just a little disturbing to see it do this and hoping nothing goes wrong when its actually cutting (doing a rapid or something?) the total machine time is over 60mins so can't exactly sit there and watch it...

Has anyone else had this happen to them? a bug??

thanks
