I forgot you have to define Sleep import. Add following somewhere before IncSrch macro or into win32.sh file where it should be:
[code:11huempy]import void Sleep(DWORD dwMilliseconds)
In the win32.sh file, I added it, ran “compile CMAC macro” and received the error message, “Error 5005: Macro being loaded is an incompatible version.”
But it did work fine when added in the Search.s file. I recompiled the Multi-Edit macros, and now the incremental search works as expected, with no CPU spiking. Thanks for your help!
