since i upgraded to 2.8.8. i noticed that layerfx behaves differently
when i start the python script for the Bevel & Emboss, the values for Depth, Size and Soften are blank
also i noticed that while the plug-in works, there is briefly a flash of a dialogue, i think it says something about Bump-Map Plug-in...
it wasnt like that before

it seems every layerfx plug-in that has a Size-value, has the same bug, they all appear blank until you change the value
note that i use the older layerfx.py, not layerfx2.8.py, because that one had the bug with the layergroups
