Some Good Advice

This strip had horrible problems.
The script was written ahead of time. The artwork was done on time. Everything got scanned and coloured with time to spare.
Then I laid the strip out in PotatoShop, started lettering and -- BAM! PotatoShop crashed. Control-Alt-Delete did nothing, Alt-Tab did nothing, Escape did nothing, the mouse did nothing... in fact, the only thing that had any effect was... the reset key. So I started laying the strip out again and saved it a few times along the way. On exactly the same speech balloon as the first time, PotatoShop crapped out, yet again. Another reset later and I ran Norton's system analysis on the drive. No major problems. I didn't even get to the same point before it crashed on me again, so this time I didn't even bother starting PotatoShop again - I ran a full Norton system scan, pulled the files off my computer, and tried to finish the strip on my girlfriend's laptop.
However, I cannot use a trackpad to save my life and gave that up in frustration after about ten minutes. I went to bed and left Norton scanning the computer for virii.
This morning, Norton had found precisely... well, nothing. I defragged the drive (and, in one of those classic Windows moments, was told that it had Finished Defragmenting C: and that after a further analysis it was Now Recommended that I Defragment C:) and had a look online to see if there was any solution to my problems. In addition to the crashes, PotatoShop had been eating large chunks of free disk space -- basically, if the programme isn't shut down properly, it doesn't trash the large temp files it creates. And if PotatoShop doesn't have enough disk space to run properly, because it's been eating it? Then it crashes itself again.
In the end, I just needed to delete the 1.5gb+ of temp files it had been leaving lying around, which freed up enough disk space to run PotatoShop without it crashing on me.
The moral here is: if everything seems to be going right, and you think you're going to finish ahead of schedule, Adobe and Microsoft both have something to say about that.
