Solution to "memory not erased: continue?" error

[randomrichard]

I am programming an 18F4550 on an EB006 at various clock settings, & crystals. I have found that although Flowcode (5.5) will recognize the chip after I have made clock settings changes, when I try immediately to "compile to chip" after saving the new version I get a "memory not erased" message and the new program is not uploaded to the chip. But if I then just "compile to chip" without any changes, the new program uploads and works. So it seems that a two-stage process: compile to hex and then to chip is a good idea with 18F chips.

Yes I do agree with you on this.
So microcontrollers appear to be affected more that others.
