LOOKUP2 not working?

[Charlie]

I have now noticed a second error in my posting - the undefined Symbol is actually "LOOK2". (NOT LOOKUP2). I really need less coffee, I think.
I did a search of my code, and Darrel's code, and there is no LOOK2.
I removed the include for Darrel's code and the problem goes away; however if I add a statement containing "LOOKUP2", even if it's not executed, the error returns, so it's a library problem, and not a coding problem, It seems that somewhere in the compile process, "LOOKUP2" gets changed to "LOOK2" and bombs.
The search continues...

Well, after poking a bit, I realized I had modified this library about a year ago to support "LCD Any Pin". I put the original back and that solved the problem. I'll have to do some digging to figure out what mistake I made, but it's clearly my issue so thanks for thinking about it and I'll take it from here. I have not noticed it in all this time, likely because I've been using 18 series parts, which don't use this lib.

Thanks also to Darrel for the gentle hint around the place to start looking.
