Are these remote views? If so...

Are either of the views parameterized?

Are they sharing a connection?

If so, are you using any progressive fetching. I don't think select will use the views that you have already opened. Have you tried to remove the USE commands and see what happens. Since I think the select is going to run the views' SQL again, perhaps if you are using progressive fecthing then the first view fetch will block the second. But...

I don't know why code would run differently in a method or a form, but, how are you looking at the data after the method executes?

Now, real stupid questions, why not use SPT or create a view that has the join in it inheriently? Doing the join at the client seems very inefficient.

Another thing to try:
USE rv1 in 0  && Data shows correctly if I Browse it

USE rv2 in 0  && Data shows correctly if I Browse it

cRV1 = dbf('rv1')
cRV2 = dbf('rv2')

SELECT v1.*, v2.* from (cRV1) v1 ;
   left outer join (cRV2) v2 on v1.IDField = v2.IDField ;
   into cursor curTemp
********************

Just some ideas...
