No, I havn't just now - from macros and from snipet. But while working with client I have been disapointed when nonе of versions of ZP > 5.3 returned me results from any kind of Gets on his machine. Only once I had saw the popup error with something "keep-alive". I had adviced the client to contact the support but he didn't.
So if you want to be shure in your work, must have the alternativity like a standart webclient request or curl (the second is better)
