Blender throws the following exception in varius situations using Kaleidoskop

Traceback (most recent call last):

AttributeError: module 'ctypes' has no attribute 'windll'

location: <unknown location>:-1

Running Blender 2.78c on MacOSX 10.12.4

In the following screenshot, clicking 'Yes' will throw the exception:

If I search for ctypes.windll.user32 in your code, there are other places you should have a look.

Hint 1: Blender is multi platform, so you should not use any windows specific dynamic libraries in addons for blender (or you should mention it in your plugin description that it will only run under windows).

Hint 2: This is only cosmetic, but you should also be aware of, that red button represents in most use cases an action which will be cancelled. Committing a change are usually associated with green buttons.

But never mind, I like the idea of your addon. ;)

Yes, that only works on Windows machine, I will fix that in the next version so that it works with all machines.

Since Blender's API does not allow colored buttons, it would not be possible to do that. Hence, I had to make it red so it stands out. I might change it to some icons that would be more understandable.
