It's not quite fair to blame Poser for a flash upgrade...but it's happened to me too. My Send in the Clones Pro doesn't work with Poser 11 and I had to seek other remedies as it seems former Poser vendors act as if they never heard of this Poser Program. One even told me he doesn't have Poser on his system. Fine. Fugazi's system seems an adequate replacement for my issue but let's see about your problem.

I am not on the update team so I can only suggest they act on a problem that will become unsupported by chrome at the very least in 2020. But first possible workaround. Would a rollback to the previous version of Flash solve your issues? It's not the jiffy response from Adobe you were hoping for but you know the Poser world is in flux right now thanks to the takeover by Rendo (Thanks Renderosity! Whew!).

P.S. I'm on a tight budget too. Hope the below helps.
