Has anyone used one of these units with picbsic pro?

I have connected the display the same way that I would with a standard LCD as per manual.

Then using lcdout "hello World" I can get a standard display to work.

Then replacing the standard lcd with the winstar 20x4 oled

The oled is blank.

I have managed to get something out of the display Greek and Chinese letters so the unit is working there seems to be a problem with initalizing the oled.

I have a 18f452 as mentioned wired as per manual and rw wired to ground, not a pic pin as not using lcdin.

I have tried changing lcd pause command etc.

Just a little stumped, as it will work perfectly on a standard lcd then plug in the oled and its either chneese or nothing.

Any help much appreciated.
