Font Reserve Client 1.7.4 is as buggy, buggier maybe, than the previous. And Extensis knows it, and they have no timeline for fixing it.
Their plugin makes InDesign 2 files incompatible with InDesign CS! They admitted this on the phone and said only that they are "aware of the problem".
InDesign 2 files created with the Font Reserve plugin will hang up when you try to open them in InDesign CS with the FR plugin.
Their suggested workaround is to turn font reserve off, disable all the plugins, open all your ID2 docs, delete the plugin data, resave them all as IDCS, then turn all the font reserve stuff back on and then maybe it'll work.
And we thought this software was to streamline work, not overcomplicate it.
I've never used a worse font manager in my life, and I've been here since their first version of suitcase.
