Problem with multi-select attributes

[David_F]

I'm having a problem with mult-select attributes. If I choose the "Allow multiple selection" option, I am not able to select anything - I choose one of the values, the checkbox remains blank. This thread here:
https://www.kinook.com/Forum/showthread.php?t=5633 suggests the problem was fixed in 6.0.0.6.

My installation shows 6.0.0.3 as the exe number - but it is the only version I can see, I downloaded it yesterday from the Kinook downloads page. Is there a more recent version somewhere?
