Adafruit 4x20 LCD

It seems the cursor method of the LCD_4x20 (Adafruit, OLED) component doesn't work. Whenever the simulation calls the method, it hangs.
Am I doing something wrong?
If not, when can I expect this bug to be fixed?

Seems to work OK for me,
Did you first call Start()?
Could you post a project file, *.fcfx?

Yes, in the 'Startup' macro as shown below.
The 'Main' calls 'Startup' which calls 'Pgm' when the 'PGM' key is pressed. It hangs at the first instance of the cursor method.

btw: This program works without issue with the generic 4x20 LCD component.

Thanks, perfect!
Probably won't get chance to look at this until return to office 2nd Jan.

Please use the attached updated component, drop into your Flowcode /components directory.
(The sim Cursor function was waiting for the ready pin - this has now been removed)
Thanks
