I will point out that your code is bad programming, because you are trying to clean out your labels by destroying the parent frame, still leaves the old labels laying around, and this will cause a memory gain everytime you do it. Using $widget->destroy usually is a bad thing in Tk. You may be able to get away with it, if you run packForget on all children of the frame, then destroy all the children. You are better off, NOT destroying the frame, just empty it then refill it.
/me slaps head. Never thought of that - thanks. Back to the drawing board to do it properly :-) and since this is AFAICT at least the second time I've been corrected on that, I've added it here: Re: Stupid mistakes I repeatedly make

[Eily]: marto you just need a longer cable :P
[Corion]: marto: Yeah, but I'm somewhat wary of installing random USB drivers downloaded from , Google Drive or whatever, so Linux wins there due to there being no conflicts and me just having to edit one text file in the worst case, to add the USB vendor
[hippo]: Long USB cable FTW.
[Corion]: Eily: I've thought of that, but I don't like running long cables through the appartment because sooner or later I'll trip over it, pulling at least one device off its stand :)
[marto]: hmm, may have to patch CPAN::Meta to move from search.cpan to metacpan in the META.json/yml files
[Corion]: marto: Heh - it seems that they plan to keep the links alive for a long time. But still, I plan on moving PM to use/generate the new links
[Corion]: And I think it's better to generate links to the new world instead of keeping the older links alive by generating new versions of them ;)
[marto]: yeah, I guess it's supposed to be a permanent redirect, but better to make the move where possible
