Hi Larry,

Try to run

DO (HOME () + "VFPCLEAN.APP")

If it doesn't help, try suggestion from Intellisense C5 on custom methods Message #751218.

>Anyone else here get a C000005 error when attempting to complete an intellisense reference (i.e. THISFORM.BlahFunction(tcParm))?
>
>I have consistently been encountering this just as I type the open parenthesis. At first I thought it was VFP doing it when I created a new method and then referencing. Now it is doing it all the time, even to existing commands.
>
>Thanks in advance for your help on this issue.
