'Write when you're inspired' is the advice; it's a shame that I'm currently inspired by an irksome piece of technology rather than some wondrous facet of creation that deserves praise.
So, the gripe I have is with Flickr's desktop uploaders: they just haven't worked since version 2.3.1 for the Mac. Further, since I invariably feel excited by the prospect of an updated piece of software, each time a new version is released I get duped into trying it out (the current version is 3.2.1). The final straw is that they have also now removed version 2.3.1 from their web site.
This evening I spent half an hour hunting through the Help Forums for version 2.3.11, and fruitlessly trying out the later evolutions up to the present 3.2.1.
I'm still using 2.3.1.
