plotBed hangs on large bedfile

[TCBroad]

I'm trying to plot a bedfile with chromstart = 4077 and chromend = 2153224, but it never completes. It seems to hang somewhere chromend = 440,000 and 450,000. values lower than this take around 1 min on my pc. I left it overnight running the full amount but it never finished.

Is there any way around this?

Thanks!
