if I set fixed heights for those elements, won't I lose the responsive characteristics? (that's why I didn't' do it in the first place)

I'm building my galleries using the javascript in your resizable gallery example. When I first open the gallery it doesn't resize, I have to drag the window a little bit, either expand or contract it,  and then the gallery resizes. I've tested this on numerous different machines, safari, Chrome, IE and it does it on all.
Here's an example of one: http://bretwills.com/BWR/liquid/index.html
Any thoughts on how to fix it?
TIA

Safari is Version 6.1.2 (7537.74.9) and I'm on OS 10.7.5
I will say that Safari does act a little glitchy since a recent upgrade on this machine. I have another Mac running 10.8xxx and another one running Maverick so out of my own curiosity I'll check on the others today.
Thanks for your (as always – I've been a customer for years.) great customer support.
I upgraded to pro yesterday.

Yes I see a flash during the transitions on the embedded gallery and flikr gallery on my machine and safari, but again not chrome. (the full browser version looks fine) I restarted everything, cleared cache, etc. I guess its a local issue to my computer.

ok-that did fix it. thanks very much.
any idea why it's blinking in safari?

I also just noticed that in Safari that gallery flashes between slides

I'm working on a test page using juice box  and I'm using a pure css drop down menu throughout the site. On the long drop down as soon as the mouse enters the gallery area the menu breaks. see here on the 'galleries' menu item:  http://bretwills.com/BWR/JB1/jblayout3purefix.html

I'm wondering if there are any known conflicts? (I validated the code this time . . .)

I tried it on various browsers and also on the regular embed code and with code like "View Resizable Gallery with Top Menu Example" you pointed me to before , all behave the same.

TIA

yes – I see the issue now. sorry about that. closing the tag makes it act normally.

I'm switching over my website from simple viewer to juice box, and I'm having having an issue where my embedded galleries are cutting off in chrome and safari. they seem to work fine in firefox. (that's all I've tested so far.) Any insight would be appreciated. Here's the test page I'm working on:
