Bug in Plot?

I recently upgraded to v 6.0.2. A plotting program I wrote years ago which has worked on many previous versions suddenly broke. I seem to have isolated the following problem: For me, this command produces a simple plot: a = 0.25; Plot[1 - Exp[-a * t], {t, 0, 10}] As does this: a = 0.25; Plot[1 - Exp[-a * t], {t, 0.5, 10}] As does this: a = 0.0025; Plot[1 - Exp[-a * t], {t, 0, 1000}] But this causes Mathematica on my machine to hang indefinitely: a = 0.0025; Plot[1 - Exp[-a * t], {t, 50, 1000}] I have to quit and re-start the kernel to recover. Can anyone reproduce this behavior? If so, can anyone suggest why this happens, or suggest a work around? Thanks is advance for all help with this. John Stone (v 6.0.2 / Mac OS-X 10.5.2)
