No worry. This tests shows that there's a loop in the data structure reference (See https://metacpan.org/pod/Test::Memory::Cycle#SYNOPSIS for more explanation). This may be a problem as memory loop cannot be garbage collected which may lead to a memory leak. With TkU, a loop may be hard to spot as callback function are likely to be involved. I'll check this out. All the best
