ImageCrop - not a bug sorry

[Skymil]

I'm not very sure about this bug. When ImageCrop is defined (with the meter IMAGE), the picture disappears, whatever the config.
I've tried many configs (for example ImageCrop=0,0,1,1 ; ImageCrop=150, 150, 150, 150, 5 ; ...).
Maybe I didn't understand how it works. However, one time, when I refreshed, a cropped picture appeared but then disappeared at the next refresh...
I'm using Rainmeter 2.3.0 r1406 64-bit.
Edit:
Ok, the issue has resolved itself and I didn't understand why...
