Hi,

I spotted this on Surpac 2025 Refresh2 as well as Surpac 2026: when running Block model > Estimation > Inverse Distance, the "Model name" input field is not large enough to receive a standard path ... as a consequence the model file is not found.

Renaming the block model file (to shorten the filename) fixes the issue:

The model file paths are: 
E:\\Surpac\\DatasetViragoSmallIDW\\virago_small_attribute_compression.mdl (not working)
E:\\Surpac\\DatasetViragoSmallIDW\\m.mdl (working)
