I have the following error:
Error: Spider Monkey Panel v1.6.1 (Lastfm Cover: Lastfm Cover by zeremy)
CheckMenuRadioItem failed:
Index is out of bounds
File: thumbs.js
Line: 345, Column: 25
Stack traces:
_thumbs/this.rbtn_up@thumbs.js:345:25
_panel/this.rbtn_up@panel.js:85:11
on_mouse_rbtn_up@lastfm_cover.js:197:18
The error occurs when I right-click on the "Panel properties" menu and change the value from 3 to 4 in the "THUMBS.ASPECT" field
The problem also occurs in the original smoralis footuner-master skin.



4 is an invalid value.
Valid values are 0,1,2,3.
panel.m.AppendMenuItem(MF_STRING, 1510, 'Crop (focus on centre)');
panel.m.AppendMenuItem(MF_STRING, 1511, 'Crop (focus on top)');
panel.m.AppendMenuItem(MF_STRING, 1512, 'Stretch');
panel.m.AppendMenuItem(MF_STRING, 1513, 'Centre');
panel.m.CheckMenuRadioItem(1510, 1513, this.properties.aspect.value + 1510);
