Hi Michael and everyone.

I can confirm the same issue raised by Finema :


1•Click lightbulb to open MoI v4, MoI works normally, draw a circle, square, etc.
2•Click lightbulb to "hide" v4.
3•Click lightbulb to "unhide" v4.
The dialog window in the upper righthand corner no longer functions. It is blank, or frozen depending upon state before hide/unhide.

I use Windows 10 Pro 64 Bit.

Thanks.
