TBitmap and Memory Overwrite

This is realated to my problem in object pascal section:      Strange
FindComponent Bug

   * I would like to create a DIB Bitmap from scratch, (DIB: because I'm
     using Scanline) but I've had some problems (this is an in house
     program so I have not worked at it that hard)
   * Now that I have my Tbitmap I'm Drawing Circles and (I Think) if the
     circles are beyond the boundary of the Bitmap enough I create a
     Memory Conflict which shows up later with Findcomponent.

Any Comments Please.
