a picture causes the game to crash!

I browsed through somel older posts and couldn't find anything about this. I am working on a game, and have drawn 25 previous pictures with no problems. Tonight, however, I encountered a problem with number 26. It is a picture of a church, slightly more detailed than other pictures. I ran the game several times, to make sure proportions were accurate. After adding priority lines, however, the next time I tested the game I got this message:
     "c:\oldgames\curtsq~1/sciv.exe
     the ntvdm cpu has encountered an illegal instruction
     cs: 4c9e IP:68c9 OP: 63 72 69 70 74
     choose close to terminate the application."
Does anybody know what could be causing this? Thanks.

How large is the picture resource? Depending on the interpreter version, sometimes they are limited to 13K~35K. Also, how are you using your fills? If you use a lot of flood fills in detailed areas, it could possibly cause a stack overflow like AGI.

Thanks! I believe the crash was due to overuse of the fill button. I had two lines of slightly different angles conjoining to form the roof, and after filling the main roof section, I used "fill" to fill in the remaining 2 pixel areas, as well. After changing those offsets to the pen button, the game worked fine. Thanks for your help.
