I ran into a bit of a problem when testing at a 25NL HU table. I only got to test it a few times because the individual left, and haven't been able to get anyone else to sit HU to try it again yet.
Here's a screenshot:

Basically, anytime villain raised to $0.75 (3x) and I was in the BB, that error message would popup. I'm assuming it's because '$1' is being misread by the OCR as 'SI'. Didn't seem to have this problem anywhere else. But it also might arise in a 6m/FR BvB situation where SB opens for 3x, and we are in the BB (just guessing).
For reference sake, I have made no changes to the default OCR settings in Skins > Advanced. OCR is still enabled there, Scaling Type "BL", Scale "3", Remove Character Count "4", Sharpen is unchecked.
